-
-This file provides guidance to Claude Code (claude.ai/code) when working with code in this repository.
-
-## Project Overview
-
-@design.estate/dees-catalog is a comprehensive web components library built with TypeScript and LitElement. It provides a large collection of UI components for building modern web applications with consistent design and behavior.
-
-## Build and Development Commands
-
-```bash
-# Install dependencies
-pnpm install
-
-# Build the project
-pnpm run build
-# This runs: tsbuild tsfolders --allowimplicitany && tsbundle element --production --bundler esbuild
-
-# Run development watch mode
-pnpm run watch
-# This runs: tswatch element
-
-# Run tests (browser tests)
-pnpm test
-# This runs: tstest test/ --web --verbose --timeout 30 --logfile
-
-# Run a specific test file
-tsx test/test.wysiwyg-basic.browser.ts --verbose
-
-# Build documentation
-pnpm run buildDocs
-```
-
-### Testing Notes
-- Test files follow the pattern: `test.*.browser.ts`, `test.*.node.ts`, or `test.*.both.ts`
-- Browser tests run in a headless browser environment
-- Use `--logfile` option to store logs in `.nogit/testlogs/`
-- For debugging, create files in `.nogit/debug/` and run with `tsx`
-
-## Architecture Overview
-
-### Component Structure
-The library is organized into several categories:
-
-1. **Core UI Components** (`dees-button`, `dees-badge`, `dees-icon`, etc.)
-   - Basic building blocks with consistent theming
-   - All support light/dark themes via `cssManager.bdTheme()`
-
-2. **Form Components** (`dees-form`, `dees-input-*`)
-   - Complete form system with validation
-   - Base class `DeesInputBase` provides common functionality
-   - Form data collection via `DeesForm` container
-
-3. **Layout Components** (`dees-appui-*`)
-   - Application shell components
-   - `DeesAppuiBase` orchestrates the entire layout
-   - Grid-based responsive design
-
-4. **Data Display** (`dees-table`, `dees-dataview-*`, `dees-statsgrid`)
-   - Complex data visualization components
-   - Interactive tables with sorting/filtering
-   - Chart components using ApexCharts
-
-5. **Overlays** (`dees-modal`, `dees-contextmenu`, `dees-toast`)
-   - Managed by central z-index registry
-   - Window layer system for proper stacking
-
-### Key Architectural Patterns
-
-#### Z-Index Management
-All overlay components use a centralized z-index registry system:
-- Definition in `ts_web/elements/00zindex.ts`
-- Dynamic z-index assignment via `ZIndexRegistry` class
-- Components get z-index from registry when showing
-- Ensures proper stacking order (dropdowns above modals, etc.)
-
-#### Theme System
-- All components support light/dark themes
-- Use `cssManager.bdTheme(lightValue, darkValue)` for theme-aware colors
-- Consistent color palette defined in `00colors.ts`
-
-#### Component Demo System
-- Each component has a static `demo` property
-- Demo functions in separate `.demo.ts` files
-- Showcase pages aggregate demos (e.g., `input-showcase.ts`)
-
-#### WYSIWYG Editor Architecture
-The WYSIWYG editor uses a sophisticated architecture with separated concerns:
-- **Main Component**: `dees-input-wysiwyg.ts` - Orchestrates the editor
-- **Handler Classes**:
-  - `WysiwygInputHandler` - Handles text input and block transformations
-  - `WysiwygKeyboardHandler` - Manages keyboard shortcuts and navigation
-  - `WysiwygDragDropHandler` - Manages block reordering
-  - `WysiwygModalManager` - Shows configuration modals
-  - `WysiwygBlockOperations` - Core block manipulation logic
-- **Global Menus**: 
-  - `DeesSlashMenu` and `DeesFormattingMenu` render globally to avoid focus issues
-  - Singleton pattern ensures single instance
-- **Programmatic Rendering**: Uses manual DOM manipulation to prevent focus loss
-
-### Component Communication
-- Custom events for parent-child communication
-- Form components emit standardized events (`change`, `blur`, etc.)
-- Complex components like `DeesAppuiBase` re-emit child events
-
-### Build System
-- TypeScript compilation with decorators support
-- Web component bundling with esbuild
-- Element exports in `ts_web/elements/index.ts`
-- Distribution builds in `dist_ts_web/`
-
-## Important Implementation Details
-
-### When Creating New Components
-1. Extend `DeesElement` from `@design.estate/dees-element`
-2. Use `@customElement('dees-componentname')` decorator
-3. Implement theme support with `cssManager.bdTheme()`
-4. Create a demo function in a separate `.demo.ts` file
-5. Export from `elements/index.ts`
-
-### Form Input Components
-1. Extend `DeesInputBase` for form inputs
-2. Implement `getValue()` and `setValue()` methods
-3. Use `changeSubject.next(this)` to emit changes
-4. Support `disabled` and `required` properties
-
-### Overlay Components
-1. Import z-index from `00zindex.ts`
-2. Get z-index from registry when showing: `zIndexRegistry.getNextZIndex()`
-3. Register/unregister with the registry
-4. Use `DeesWindowLayer` for backdrop if needed
-
-### Testing Components
-1. Create test files in `test/` directory
-2. Use `@git.zone/tstest` with tap-bundle
-3. Test in browser environment for web components
-4. Use proper async/await for component lifecycle
-
-## Common Patterns and Pitfalls
-
-### Focus Management
-- WYSIWYG editor uses programmatic rendering to prevent focus loss
-- Use `requestAnimationFrame` for timing-sensitive focus operations
-- Avoid reactive re-renders during user input
-
-### Event Handling
-- Prevent event bubbling in nested interactive components
-- Use `pointer-events: none/auto` for click-through behavior
-- Handle both mouse and keyboard events for accessibility
-
-### Performance Considerations
-- Large components (editor, terminal) use lazy loading
-- Charts use debounced resize observers
-- Tables implement virtual scrolling for large datasets

+
+## 2026-01-03 - 3.28.1 - fix(appui)
+adjust layout and spacing in app UI components: fix activity log overflow, contain main content overscroll, and refine secondary menu padding/transition
+
+- ts_web/elements/00group-appui/dees-appui-activitylog: removed host max-width, added overflow:hidden and set .maincontainer width to 280px to prevent horizontal overflow
+- ts_web/elements/00group-appui/dees-appui-maincontent: added overscroll-behavior: contain to .content-area to prevent scroll chaining/overscroll

+
+## 2026-01-01 - 3.27.1 - fix(dees-actionbar)
+always render actionbar wrapper and delay adding visible class to ensure grid/opacity animations run reliably
+
+- Always render the actionbar wrapper (.actionbar-item and .actionbar-content) instead of returning early so grid-template-rows and opacity transitions can animate.
+- Use optional chaining for current bar access (bar?.type, bar?.timeout) to avoid runtime errors when no bar is present.
+- Adjust styles and structure: set :host display:block; move background/border to .actionbar-item; add .actionbar-content with min-height/opacity and transitions.
+- Make processQueue asynchronous and await updateComplete, then add the 'visible' class inside requestAnimationFrame so the CSS transition is triggered after render.
+
+## 2026-01-01 - 3.27.0 - feat(services)
+introduce DeesServiceLibLoader to lazy-load heavy client libraries from CDN and update components to use it
+
+- Add DeesServiceLibLoader singleton (ts_web/services/DeesServiceLibLoader.ts) to lazily load and cache libraries via jsDelivr ESM: xterm, xterm-addon-fit, highlight.js, ApexCharts, and Tiptap.
+- Inject xterm CSS dynamically to avoid shipping xterm styles in the initial bundle.
+- Expose helper methods preloadAll() and isLoaded(), and typed bundle interfaces (IXtermBundle, IXtermFitAddonBundle, ITiptapBundle).
+- Update components to use runtime-loaded modules: dees-chart-area, dees-dataview-codebox, dees-input-richtext, wysiwyg code block, dees-workspace-terminal, terminal-tab-manager, dees-workspace-terminal-preview.
+- TerminalTabManager now requires setXtermModules(...) before creating tabs and will throw if not initialized; workspace terminal now initializes and passes the loaded modules.
+- Replace direct runtime imports of heavy libs with typed imports and runtime-loaded bundles to reduce initial bundle size and improve load performance.
+
+## 2026-01-01 - 3.26.1 - fix(dees-actionbar)
+animate actionbar hide using grid-template-rows and wait for animation before clearing state
+
+- Switch host layout from block/max-height to grid using grid-template-rows for open/close transitions
+- Add min-height: 0 to .actionbar-item to prevent flex children overflow and collapsing
+- Introduce async hideCurrentBar() that removes 'visible', sets isVisible=false, waits 220ms then clears currentBar and currentResolve
+- processQueue() now calls hideCurrentBar() asynchronously instead of clearing state immediately
+
+## 2026-01-01 - 3.26.0 - feat(workspace)
+add external file change detection, conflict resolution UI, and diff editor
+
+- Watch open files for external changes with debounced file watchers (startWatchingFile/stopWatchingFile/stopAllFileWatchers).

+- Introduce dees-workspace-diff-editor component and export it; support comparing and resolving diffs (diff-resolved / diff-closed events).
+- Add setContentExternal in dees-workspace-monaco to update editor content from external sources while optionally preserving cursor, selections and scroll position.
+- Start/stop file watchers when files are opened/closed and integrate diff view and actionbar into the workspace UI for seamless conflict handling.
+
+## 2026-01-01 - 3.25.0 - feat(dees-actionbar)
+add action bar component and improve workspace package update handling
+
+- Introduce dees-actionbar component (dees-actionbar.ts) with interfaces, queueing, timed auto-trigger and demo usage
+- Add actionbar.interfaces.ts and index export; export dees-actionbar from elements index
+- Enhance workspace bottombar: add pendingPackageUpdate flag, process-complete handler, and connected/disconnected listeners to auto-refresh package status after updates
+- Make pnpm outdated checking robust by streaming output via a reader and adding a 10s timeout to avoid hanging; handle timeout and stream cancellation
+- Update package update commands to include '--latest' for updatePackage and updateAllPackages, and show 'Checking...' label during checks

+
+## 2026-01-01 - 3.24.0 - feat(workspace)
+add workspace bottom bar, terminal tab manager, and run-process integration
+
+- Add dees-workspace-bottombar component and export; bottom bar emits run-process events to launch processes.
+- Introduce terminal interfaces (IRunProcessEventDetail, ITerminalTab, ICreateTerminalTabOptions, etc.) and a TerminalTabManager to manage multiple terminal tabs and lifecycle.
+- Integrate bottombar into dees-workspace: layout refactor (workspace-outer), move/adjust resize handles and panels, and handle @run-process to create terminal tabs and focus terminal panel.
+- Enhance dees-workspace-terminal: tabbed terminal UI, new public APIs (createProcessTab, writeToTab, sendInputToTab), theme updates, and improved disposal/cleanup behavior.
+- Update module exports to include bottombar and additional terminal sub-exports (interfaces, terminal-tab-manager).
+
+## 2025-12-31 - 3.23.0 - feat(workspace)
+add resizable file tree and terminal panes with draggable handles and public layout APIs
+
+- Introduce reactive state for currentFileTreeWidth, currentTerminalHeight, isDraggingFileTree and isDraggingTerminal
+- Add mouse event handlers (mousedown/move/up) to drag-resize the file tree and terminal with min/max clamping
+- Dispatch window resize event after resizing to notify Monaco/editor of layout changes
+- Clean up resize event listeners in disconnectedCallback
+- Initialize current sizes from component properties in firstUpdated
+- Expose public layout methods: setFileTreeWidth, setTerminalHeight, resetLayout
+
+## 2025-12-31 - 3.22.0 - feat(workspace)
+add resizable markdown editor/preview split with draggable handle and markdown outlet styling/demo
+
+- Introduce a flexible split layout for the workspace markdown editor with a draggable resize handle (splitRatio, minPanelSize, dragging state, mouse handlers and cleanup).
+- Enhance dees-workspace-markdown: switch from grid to flex, add resize handle UI, prevent pointer selection while dragging, notify Monaco on resize.
+- Add comprehensive styling and demo content for dees-workspace-markdownoutlet (dark/light themed markdown styles, syntax highlighting classes, and demo scenarios).
+- Fix typescript-intellisense monaco model update: only set model value when content actually changed to avoid cursor resets.
+- Add markdown outlet demo helper and numerous screenshot/image assets (.playwright-mcp) for demos/documentation.
+
+## 2025-12-31 - 3.21.0 - feat(terminal)
+add dynamic bright/dark theming for terminal components and terminal preview
+
+- Add bright/dark theme PNG assets under .playwright-mcp for previews.
+- Replace hardcoded terminal background/colors with cssManager.bdTheme in workspace terminal and preview styles.
+- Introduce getTerminalTheme helper to compute xterm theme for bright/dark modes.
+- Subscribe to themeManager.themeObservable and apply updates to xterm (terminal.options.theme) so terminals update live on theme change.
+- Remove hardcoded background property/CSS var and unused background accessor from workspace terminal.
+- Ensure proper cleanup: unsubscribe theme subscriptions and dispose terminals in disconnectedCallback.
+
+## 2025-12-31 - 3.20.1 - fix(dees-workspace)
+fix demo wrapper and workspace layout; always render terminal preview
+
+- Import @design.estate/dees-wcctools/demotools and wrap demo content in <dees-demowrapper>
+- Create an absolute-positioned container so the dees-workspace fills 100% height/width
+- Always render dees-workspace-terminal-preview (use empty command when none) to avoid conditional rendering issues
+- Set a fixed height (200px) for the terminal preview in the initializing state
+- Add Playwright demo asset .playwright-mcp/dees-workspace-demo-4k.png
+
+## 2025-12-31 - 3.20.0 - feat(workspace)
+rename editor components to workspace group and move terminal & TypeScript intellisense into workspace
+
+- Renamed components and modules from 00group-editor/dees-editor-* to 00group-workspace/dees-workspace-* (e.g. dees-editor-monaco -> dees-workspace-monaco).
+- Moved terminal implementation from dees-terminal to dees-workspace-terminal and updated related imports/usages.
+- Moved TypeScript intellisense manager into 00group-workspace and updated paths.
+- Updated ts_web elements index to export 00group-workspace instead of 00group-editor and adjusted internal imports accordingly.
+- Updated scripts/update-monaco-version.cjs to write MONACO_VERSION into the new workspace path and updated log tags.
+
+## 2025-12-31 - 3.19.1 - fix(intellisense)
+Debounce TypeScript/JavaScript IntelliSense processing and cache missing packages to reduce work and noisy logs
+
+- Add 500ms debounce in editor workspace to avoid parsing on every keystroke
+- Introduce notFoundPackages cache to skip repeated filesystem checks for packages without types
+- Clear not-found cache when scanning node_modules so newly installed packages are re-detected
+- Remove noisy console logs and make file/directory read errors non-fatal (ignored)
+- Simplify processContentChange signature (removed optional filePath) and remove manual diagnostic refresh logic
+
+## 2025-12-31 - 3.19.0 - feat(dees-editor-workspace)
+improve TypeScript IntelliSense, auto-run workspace init commands, and watch node_modules for new packages
+
+- Execute an onInit command from /npmextra.json on workspace initialization (e.g., run pnpm install).
+- Add npmextra.json and an import test file (importtest.ts) plus a sample dependency in the scaffold to test package imports.
+- Add node_modules watcher with debounce to auto-scan and load package types after installs.
+- Enhance TypeScript IntelliSense: recursively load all .d.ts files from packages and @types packages, add package.json as extra lib, and log progress/errors for debugging.
+- Change processContentChange signature to accept optional filePath and trigger a diagnostic refresh when new types are loaded.
+- Expose scanAndLoadNewPackageTypes to scan top-level and scoped packages and load their types.
+- Add start/stop logic for the node_modules watcher in workspace lifecycle to avoid leaks and handle cleanup.
+
+## 2025-12-31 - 3.18.0 - feat(filetree)
+add filesystem watch support to WebContainer environment and auto-refresh file tree; improve icon handling and context menu behavior
+
+- Add IFileWatcher interface and watch(...) signature to IExecutionEnvironment.
+- Implement watch(...) in WebContainerEnvironment using WebContainer's fs.watch and return a stop() handle.
+- dees-editor-filetree: start/stop file watcher, debounce auto-refresh on FS changes, cleanup on disconnect, and track last execution environment.
+- Add clipboard state (copy/cut) and related UI/menu enhancements for file operations (new file/folder, rename, delete, copy/paste).
+- dees-icon: default to Lucide icons when no prefix is provided.
+- dees-contextmenu: remove 'lucide:' prefix usage in templates and avoid awaiting windowLayer.destroy() to provide instant visual feedback.
+- Menu item shape adjusted (use { divider: true } for dividers) and various menu icon name updates.
+
+## 2025-12-31 - 3.17.0 - feat(editor)
+add file explorer toolbar, empty-space context menu, editor auto-save, save-all, and keyboard save shortcuts
+
+- Added filetree toolbar with New File / New Folder actions and toolbar styling
+- Added right-click context menu for empty filetree space to create files/folders
+- Implemented editor menu button with context menu (Auto Save toggle, Save, Save All)
+- Added auto-save toggle with 2s interval and cleanup on disconnect
+- Implemented Save and Save All APIs that persist files and update IntelliSense manager
+- Added keyboard shortcuts: Cmd/Ctrl+S to save active file and Cmd/Ctrl+Shift+S to save all
+- Made tabs scrollable with a tabs container and added an editor menu button
+
+## 2025-12-30 - 3.16.0 - feat(editor)
+improve TypeScript IntelliSense and module resolution for Monaco editor
+
+- Add file cache (fileCache) and getFileContent() for synchronous access to project files
+- Track and dispose Monaco extra libs (addedExtraLibs) and register project files via addExtraLib to enable TypeScript module resolution
+- Add addFileAsExtraLib logic to register .ts/.tsx files also under .js/.jsx paths so ESM imports resolve to TypeScript sources
+- Use ModuleResolutionKind.Bundler fallback to NodeJs and set compilerOptions (baseUrl '/', allowImportingTsExtensions, resolveJsonModule) to improve resolution
+- Adapt executionEnvironment API usage to readDir/readFile and check entry.type ('directory'|'file') instead of isDirectory/isFile
+- Add a debugging/screenshot asset: .playwright-mcp/module-resolution-fixed.png
+
+## 2025-12-30 - 3.15.0 - feat(editor)
+enable file-backed Monaco models and add Problems panel; lazy-init project TypeScript IntelliSense
+
+- dees-editor-monaco: add `filePath` property and create/get Monaco models with file:// URIs so editors are backed by real models; sync content into models and handle model switching when filePath changes; enable hover config and improved lifecycle handling.
+- dees-editor-workspace: add bottom 'Problems' panel and panel tabs (terminal/problems), diagnosticMarkers state, marker listener, UI for problem list, and navigation to file/position when a problem is clicked; initialize IntelliSense lazily when a file is opened.
+- typescript-intellisense: index project .ts/.js files from the virtual filesystem into Monaco models for cross-file resolution, enable allowNonTsExtensions and set eager model sync so TypeScript processes models eagerly.
+- General: improved handling for language changes, model language switching, and deferred initialization of the IntelliSense manager.
+- Add Playwright test images (workspace screenshots) used by CI/tests.
+
+## 2025-12-30 - 3.14.2 - fix(editor)
+bump monaco-editor to 0.55.1 and adapt TypeScript intellisense integration to the updated Monaco API
+
+- Bumped dependency monaco-editor from 0.52.2 to 0.55.1 in package.json.
+- Generated MONACO_VERSION module updated to 0.55.1 and moved target to ts_web/elements/00group-editor/dees-editor-monaco/version.ts.
+- Refactored TypeScript IntelliSense code to use a typed Monaco TS API (added IMonacoTypeScriptAPI, tsApi getter, and replaced direct monaco.languages.typescript.* calls).
+- Added test/workspace screenshot .playwright-mcp/workspace-test.png (binary asset).
+
+## 2025-12-30 - 3.14.1 - fix(build)
+bump @webcontainer/api and enable skipLibCheck to avoid type-check conflicts
+
+- Updated @webcontainer/api from 1.2.0 to 1.6.1
+- Added "skipLibCheck": true to tsconfig.json compilerOptions to suppress external library type errors
+- No breaking changes expected; this is a build/dev fix
+
+## 2025-12-30 - 3.14.0 - feat(editor)
+add modal prompts for file/folder creation, improve Monaco editor reactivity and add TypeScript IntelliSense support
+
+- Replace window.prompt for new file/folder with DeesModal + DeesInputText (showInputModal) to provide a focused modal input UX.
+- Monaco editor: add language property, handle external content updates without emitting change events (isUpdatingFromExternal), dispatch 'content-change' events, and apply language changes at runtime.
+- Add TypeScriptIntelliSenseManager to load .d.ts/type packages from the virtual filesystem (/node_modules), parse imports, load @types fallbacks, and add file models to Monaco for cross-file IntelliSense.
+- Workspace demo now mounts an initial TypeScript project and exposes initializationPromise to wait for external setup; workspace initializes IntelliSense and processes content changes to keep types up to date.
+- Export typescript-intellisense from workspace index so the manager is available to consumers.
+
+## 2025-12-30 - 3.13.1 - fix(webcontainer)
+prevent double initialization and race conditions when booting WebContainer and loading editor workspace/file tree
+
+- Add loadTreeStarted flag in dees-editor-filetree to avoid double-loading the file tree and reset it on refresh or on error to allow retries.
+- Add initializationStarted flag in dees-editor-workspace to prevent duplicate workspace initialization and reset it on initialization failure to allow retry.
+- Make WebContainerEnvironment use a shared singleton container and a bootPromise so only one WebContainer boot runs per page; instances wait for an ongoing boot instead of booting again.
+- Reset bootPromise/sharedContainer on boot failure and clear them on teardown so subsequent attempts can retry cleanly.
+
+## 2025-12-30 - 3.13.0 - feat(editor/runtime)
+Replace bare editor with Monaco-based editor and add runtime + workspace/filetree integration
+
+- Removed dees-editor-bare and replaced usages with dees-editor-monaco (includes MONACO_VERSION file).
+- Added IExecutionEnvironment interface and WebContainerEnvironment implementation (uses @webcontainer/api) to provide a browser Node/runtime API.
+- Added new components: dees-editor-filetree and dees-editor-workspace to support file tree, multiple open files, and workspace actions wired to the execution environment.
+- dees-terminal updated to accept an executionEnvironment (IExecutionEnvironment), renamed environment -> environmentVariables, provides environmentPromise (deprecated note), and now initializes/uses the provided environment to spawn shell processes and write /source.env.
+- Updated imports/usages across components (dees-input-code, dees-editor-markdown, group index exports) to use the new Monaco editor and runtime modules.
+- Behavioral breaking changes: consumers must supply an IExecutionEnvironment to components that now depend on it (e.g. dees-terminal, workspace, filetree); dees-editor-bare removal is a breaking API change.
+
+## 2025-12-30 - 3.12.2 - fix(dees-editor-bare)
+make Monaco editor follow domtools theme and clean up theme subscription on disconnect
+
+- Set initial Monaco theme from domtools.themeManager.goBrightBoolean instead of hardcoded 'vs-dark'
+- Subscribe to domtools.themeManager.themeObservable to update editor theme dynamically
+- Add monacoThemeSubscription property and unsubscribe in disconnectedCallback to avoid memory leaks
+
+## 2025-12-30 - 3.12.1 - fix(modal)
+fix modal editor layout to prevent overlap by adding relative positioning and reducing height
+
+- Added Playwright screenshots: .playwright-mcp/dees-input-code-demo.png and .playwright-mcp/modal-overlap-issue.png
+- Updated ts_web/elements/00group-input/dees-input-code/dees-input-code.ts: modal-editor-wrapper set position: relative and changed height from calc(100vh - 160px) to calc(100vh - 175px) to avoid overlap
+
+## 2025-12-30 - 3.12.0 - feat(editor)
+add code input component and editor-bare, replace dees-editor usage, and add modal contentPadding
+
+- Add new dees-input-code component (full-featured code editor input with modal, toolbar, language selector, copy and wrap toggles).
+- Introduce dees-editor-bare component and remove the legacy dees-editor implementation; update editor markdown component to use dees-editor-bare.
+- Export and include DeesInputCode in input index and include it in the unified form input types and dees-form usage.
+- Add contentPadding property to DeesModal and apply it to the modal content area (configurable modal inner padding).
+- Update element exports to point to dees-editor-bare and adjust related imports/usages.
+- Bump devDependency @design.estate/dees-wcctools from ^3.3.0 to ^3.4.0 in package.json
+
+## 2025-12-30 - 3.11.2 - fix(tests)
+make WYSIWYG tests more robust and deterministic by initializing and attaching elements consistently, awaiting customElements/firstUpdated, adjusting selectors and assertions, and cleaning up DOM after tests
+
+- Create WYSIWYG elements with document.createElement and set properties before attaching to DOM to ensure firstUpdated sees data
+- Await customElements.whenDefined and add small delays (setTimeout) so nested components finish rendering in test environments
+- Replace outdated selectors (.block.code) with .code-editor and update expectations for code block selection and language controls
+- Adjust divider expectations to check for <hr> and data-block-id instead of a divider icon; change toBeDefined -> toBeTruthy for assertions where appropriate
+- Add cleanup (document.body.removeChild) after tests to avoid leaking elements between tests
+- Relax computed font-family assertion to be platform-agnostic and verify that a fontFamily exists rather than matching 'monospace'
+- Add notes/guards around synthetic DragEvent/KeyboardEvent behavior: verify handlers/state existence and dispatch events but avoid relying on native focus/drag internals in CI
+- Update BlockRegistry render tests to assert template structure (data-block-id, data-block-type, class names) rather than final content which is populated later
+
+## 2025-12-30 - 3.11.1 - fix(tests)
+migrate tests to @git.zone/tstest tapbundle and export tap.start() in browser tests
+
+- Replaced imports from @push.rocks/tapbundle to @git.zone/tstest/tapbundle across test files
+- Replaced bare tap.start() calls with export default tap.start() in browser test files so the runner can be imported
+- Bumped devDependency @git.zone/tstest from ^3.1.3 to ^3.1.4 and removed @push.rocks/tapbundle from devDependencies
+- Changes include package.json and updates to multiple test files (11 test files)
+
+## 2025-12-30 - 3.11.0 - feat(dees-appui-tabs)
+improve horizontal tabs UX with scroll fades, hover scrollbar, and smooth scroll-to-selected
+
+- Add reactive scroll state (canScrollLeft / canScrollRight) and updateScrollState to track horizontal overflow.
+- Introduce scroll-fade gradient elements and CSS to indicate overflow on left/right edges.
+- Show a thin, styled scrollbar on hover (webkit + Firefox styling) instead of hiding it completely.
+- Auto-scroll selected tab into view using scrollTabIntoView and smooth scroll when selecting a tab.
+- Set up a ResizeObserver to recompute scroll state on container size changes and clean it up on disconnect.
+- Ensure lifecycle hooks call updateScrollState (firstUpdated/updated) so indicators stay in sync after render/fonts ready.
+
+## 2025-12-29 - 3.10.0 - feat(appui-tabs)
+add closeable tabs and auto-hide behavior for content tabs, plus API and events to control them
+
+- Add closeable tab support: IMenuItem.closeable & IMenuItem.onClose; dees-appui-tabs renders a close button, invokes onClose, and emits a 'tab-close' event.
+- Add auto-hide feature: dees-appui-tabs (autoHide, autoHideThreshold) and corresponding properties in dees-appui-maincontent/dees-appui-base to hide tabs when count ≤ threshold.
+- Expose new API: dees-appui-base.setContentTabsAutoHide(enabled, threshold) and update appconfig interface to include setContentTabsAutoHide.
+- Re-emit 'tab-close' events from dees-appui-maincontent and dees-appui-base so parent components can react to tab closures.
+- Add interactive demos (demo-closeable-tabs, demo-autohide-tabs) demonstrating the new closeable and auto-hide behaviors and controls.
+
+## 2025-12-29 - 3.9.0 - feat(dees-appui-mainmenu)
+add status badges to main menu items with theme-aware styling
+
+- Introduce .badge element and layout (min-width, height, padding, font-size, weight, border-radius) to display counts/status on menu items.
+- Add four badge variants: default, success, warning, error, using cssManager.bdTheme for light/dark color pairs.
+- Render the badge element conditionally in the menu item template when tabArg.badge is provided; hide badges when host has [collapsed] attribute.
+
+## 2025-12-29 - 3.8.0 - feat(dees-appui-base)
+add interactive demo controls to manipulate appui via view activation context
+
+- Store IViewActivationContext on the demo element (this.ctx) during onActivate
+- Add a new "Context Actions" UI section with buttons that call ctx.appui methods (toggle main/secondary menus, content tabs, collapse/expand main menu, set breadcrumbs, navigate to views, add activity entry, set/clear menu badges)
+- Include styles for ctx-actions and button variants (success, danger, hover states)
+- Change is limited to the demo file (dees-appui-base.demo.ts) and is non-breaking
+
+## 2025-12-29 - 3.7.1 - fix(dees-appui-maincontent)
+migrate main content layout to CSS Grid and enable topbar collapse transitions
+
+- Replace absolute positioning with CSS Grid on :host and .maincontainer to enable natural document flow
+- Make .topbar a grid and animate collapse via grid-template-rows; switch :host([notabs]) to grid-template-rows: 0fr instead of display:none to allow transitions
+- Set .maincontainer to display:contents and add min-height:0 on content areas and topbar children to fix overflow/scrolling and flex/grid height issues
+- Remove positional styles (position:absolute/top/left/right/bottom) so content scrolls correctly and layout is more robust
+
+## 2025-12-29 - 3.7.0 - feat(dees-contextmenu,dees-appui-tabs,test)
+Prevent double-destruction of context menus, await window layer teardown, update destroyAll behavior, remove tabs content slot, and adjust tests
+
+- Add isDestroying guard in DeesContextmenu.destroy to avoid double-destruction.
+- Await windowLayer.destroy() to ensure the window layer is fully torn down before continuing.
+- Ensure submenu timeouts are cleared and submenu.destroy() is awaited during teardown.
+- Change destroyAll to locate the root/top-level menu and destroy from the root to cascade teardown reliably.
+- Remove the .content wrapper and the <slot> output from dees-appui-tabs (demo updated to render content outside the component) — this is a breaking change to the tabs API (slotted content no longer rendered).
+- Increase test timeout in test.contextmenu-nested-close.browser.ts to 600ms to account for ~300ms windowLayer destruction + ~100ms context menu delay.
+
+## 2025-12-29 - 3.6.1 - fix(readme)
+document new App UI APIs to control main/secondary menu and content tabs visibility
+
+- Added docs for setMainMenuCollapsed(), setMainMenuVisible(), setSecondaryMenuCollapsed(), setSecondaryMenuVisible(), and setContentTabsVisible() programmatic APIs.
+- Included a TypeScript example showing how to hide secondary menu, hide content tabs, and collapse the main menu in a view's onActivate hook.
+
+## 2025-12-29 - 3.6.0 - feat(dees-appui)
+add visibility toggles for main/secondary menus and ability to show/hide content tabs; expose corresponding setters and appconfig entries
+
+- ts_web/elements/00group-appui/dees-appui-base: added boolean properties mainmenuVisible, secondarymenuVisible, maincontentTabsVisible; render main and secondary menus conditionally; pass showTabs to dees-appui-maincontent; added setter methods: setMainMenuVisible, setSecondaryMenuCollapsed, setSecondaryMenuVisible, setContentTabsVisible.
+- ts_web/elements/00group-appui/dees-appui-maincontent: added showTabs property, support for a notabs attribute via styles, updated() and firstUpdated() to apply notabs state so tabs can be hidden/shown dynamically.
+- ts_web/elements/interfaces/appconfig.ts: expanded appconfig interface to include setMainMenuVisible, setSecondaryMenuCollapsed, setSecondaryMenuVisible, setContentTabsVisible so host app can control visibility programmatically.
+- No breaking changes: defaults preserve existing behavior (menus and tabs remain visible by default).
+
+## 2025-12-29 - 3.5.1 - fix(dees-appui-view)
+remove DeesAppuiView component, its demo, documentation snippet, and related exports
+
+- Deleted component implementation: ts_web/elements/00group-appui/dees-appui-view/dees-appui-view.ts
+- Deleted demo file: ts_web/elements/00group-appui/dees-appui-view/dees-appui-view.demo.ts
+- Removed index re-export: ts_web/elements/00group-appui/dees-appui-view/index.ts (deleted) and removed export from ts_web/elements/00group-appui/index.ts
+- Removed documentation section for DeesAppuiView from readme.md
+- Breaking change: any consumers using the <dees-appui-view> component or its public API (selectTab, getMenuItems, getTabs) must be migrated to alternate components/approach
+
+## 2025-12-29 - 3.5.0 - feat(theme,interfaces)
+Introduce a global theming system and unify menu/tab interfaces; migrate components to use themeDefaultStyles and update APIs accordingly
+
+- Add a new theme module and component (00theme.ts + dees-theme) that provides CSS tokens and themeDefaultStyles to import into components
+- Migrate many components to include themeDefaultStyles in their static styles and add TODOs to replace hardcoded values with CSS variables
+- Rename ITab -> IMenuItem and replace group.tabs with group.items across interfaces and components (IMenuGroup shape changed) — this is a breaking API change
+- Remove legacy interfaces (ISecondaryMenuGroup, ISelectionOption) and update method and property types in DeesAppui* components and app config to use IMenuItem/IMenuGroup
+- Move @design.estate/dees-wcctools from dependencies to devDependencies and bump its version to ^3.3.0
+- Add numerous demo files and expand README with usage, examples and theme documentation
+
+## 2025-12-19 - 3.4.0 - feat(dees-appui-base)
+overhaul AppUI core: replace simple view rendering with a full-featured ViewRegistry (caching, hide/show lifecycle, async lazy-loading), introduce view lifecycle hooks and activation context, add activity log API/component, remove built-in router and state manager, and update configuration interfaces and demos
+
+- Removed files: app.router.ts and state.manager.ts — routing and state-persistence internals were removed (breaking).
+- ViewRegistry rewritten: supports cached instances, activate/deactivate lifecycle, canDeactivate checks, async content loading, parameterized routes, and legacy renderView kept as deprecated compatibility.
+- New interfaces added/changed: IViewActivationContext, IViewLifecycle, IActivityEntry, IActivityLogAPI, IViewLifecycleEvent; IViewDefinition.content now accepts async loaders and a cache flag; IMainMenuConfig and ITab expanded (logo, groups, badges).
+- Activity log: dees-appui-activitylog now implements IActivityLogAPI and exposes reactive entries; demo and readme updated with usage and examples.
+- App config changed: routing and statePersistence config entries removed/adjusted; defaultView moved into IAppConfig; view change and lifecycle event shapes changed (breaking).
+- Demos and documentation: dees-appui-base demo and readme added/updated to showcase new lifecycle hooks, secondary menu behavior, activity log and new APIs.
+
+## 2025-12-19 - 3.3.3 - fix(tests)
+update test imports to new dees-input-wysiwyg paths
+
+- Updated imports in test/test.wysiwyg-registry.both.ts to point to ts_web/elements/00group-input/dees-input-wysiwyg/*
+- Aligns test references with relocated WYSIWYG block handlers and block registration module; no behavior changes to implementation
+
+## 2025-12-19 - 3.3.2 - fix(build)
+update build config, bump dependencies, and adjust test import paths after element reorganization
+
+- npmextra.json: renamed gitzone entry to @git.zone/cli, moved tsdoc key to @git.zone/tsdoc, added @ship.zone/szci entry and added release registries + accessLevel
+- package.json: bumped @design.estate/dees-wcctools ^2.0.1 -> ^3.1.0, lucide ^0.560.0 -> ^0.562.0, @git.zone/tsbuild ^3.1.2 -> ^4.0.2, @types/node ^25.0.0 -> ^25.0.3
+- tests: updated import paths to follow reorganized source layout (wysiwyg files moved under elements/00group-input/dees-input-wysiwyg and dees-contextmenu moved to elements/dees-contextmenu/dees-contextmenu.js); updated BlockRegistry and blockregistration import paths
+- Purpose: align tests and build metadata with refactored element file locations and updated tool/dependency versions
+
+## 2025-12-11 - 3.3.1 - fix(dees-pdf-viewer)
+Scroll active PDF thumbnail into view after rendering and on page changes; update dependency versions
+
+- Ensure the active thumbnail is scrolled into view after thumbnails are rendered (improves sidebar navigation for dees-pdf-viewer).
+- Scroll the thumbnail into view when navigating pages if the sidebar is visible (prevents the active page from being off-screen).
+- Retain re-setup of the intersection observer for lazy-loading pages after thumbnail re-render.
+- Bumped dependencies in package.json: @design.estate/dees-wcctools -> ^2.0.1, lucide -> ^0.560.0, @git.zone/tswatch -> ^2.3.13, @types/node -> ^25.0.0.
+
+## 2025-12-09 - 3.3.0 - feat(dees-appui-base)
+Add unified App UI API to dees-appui-base with ViewRegistry, AppRouter and StateManager
+
+- Introduce ViewRegistry for declarative view registration and rendering (supports tag names, element classes and template functions).
+- Add AppRouter with hash/history/external/none modes, URL synchronization, navigate/back/forward and onRouteChange listener support.
+- Add StateManager to persist UI state (localStorage, sessionStorage or in-memory) with save/load/update/clear APIs.
+- Extend interfaces (interfaces/appconfig.ts) with IAppConfig, IViewDefinition, IRoutingConfig, IStatePersistenceConfig and IAppUIState.
+- Expose new public DeesAppuiBase methods: configure, navigateToView, getCurrentView, getUIState, restoreUIState, saveState, loadState, getViewRegistry, getRouter.
+- Maintain backward compatibility with existing property-based API and slot usage.
+- Export new modules (view.registry, app.router, state.manager) from dees-appui-base index and update element exports.
+
+## 2025-12-08 - 3.2.0 - feat(dees-simple-appdash,dees-simple-login,dees-terminal)

+
+- Standardize icon usage to Lucide prefixes in dees-simple-appdash; add fallback handling for legacy icon names
+- Revamped dees-simple-appdash sidebar: updated spacing, typography, header icon wrapper, scrollbar styling, section labels, hover/selected states, and visual indicators
+- Change 'Logout' label to 'Sign out' in dees-simple-appdash and add explicit status classes for controlbar (connected, terminal)
+- Improve terminal UX: smoother launch/close animations, updated shadow and sizing logic in dees-simple-appdash
+- Add background property to dees-terminal, sync it to a CSS variable and apply it to xterm theme for configurable terminal background
+- Redesign dees-simple-login: new header/subheader, card layout, spacing, and updated submit text to 'Sign in'
+- Bump devDependency @git.zone/tswatch to ^2.3.5
+
+## 2025-12-08 - 3.1.2 - fix(DeesAppuiMainmenu, DeesAppuiSecondarymenu)
+Add position: relative to main and secondary app UI menus to fix positioning of overlays and tooltips
+
+- ts_web/elements/00group-appui/dees-appui-mainmenu/dees-appui-mainmenu.ts: add `position: relative` to host styles
+- ts_web/elements/00group-appui/dees-appui-secondarymenu/dees-appui-secondarymenu.ts: add `position: relative` to host styles
+- Fixes incorrect positioning for absolutely positioned children (tooltips, overlays, badges) inside the main and secondary menus
+
+## 2025-12-08 - 3.1.1 - fix(dees-appui)
+Extract demos for main and secondary app menus, adjust collapsed styles and toggle placement, bump devDependency
+
+- Extracted inline demo markup into separate demo files: ts_web/elements/00group-appui/dees-appui-mainmenu/dees-appui-mainmenu.demo.ts and ts_web/elements/00group-appui/dees-appui-secondarymenu/dees-appui-secondarymenu.demo.ts and wired them up via imported demoFunc to reduce component size.
+- Moved collapse toggle button markup in both dees-appui-mainmenu and dees-appui-secondarymenu templates to after the main container to improve layout/stacking and focus behavior.
+- Adjusted collapsed logo/heading styles: removed extra padding/gap and hide logo text using display:none for a cleaner collapsed state.
+- Bumped devDependency @git.zone/tswatch from ^2.3.1 to ^2.3.2 in package.json.
+
+## 2025-12-08 - 3.1.0 - feat(dees-appui)
+Add collapsible/compact mode to AppUI sidebars (mainmenu & secondarymenu) with toggles, tooltips and improved z-index stacking
+
+- Add collapsed property to dees-appui-mainmenu and dees-appui-secondarymenu (reflect: true) to enable compact horizontal mode.
+- Add floating collapse toggle buttons and public toggleCollapse() methods on mainmenu and secondarymenu; these dispatch 'collapse-change' events (bubbles & composed).
+- Expose and track collapse state in dees-appui-base via mainmenuCollapsed and secondarymenuCollapsed properties; bind states to child components and re-emit collapse-change events as mainmenu-collapse-change and secondarymenu-collapse-change.
+- Implement collapsed styles and animations: reduced sidebar widths, hide/compact labels and headers, center icons, hide badges, and add smooth width/opacity transitions.
+- Add tooltips that appear for tabs/items when sidebars are collapsed to preserve discoverability.
+- Adjust layout grid in DeesAppuiBase (use auto columns) and add explicit z-index layering to ensure proper stacking order of mainmenu, secondarymenu, maincontent and activitylog.
+
+## 2025-12-08 - 3.0.1 - fix(dees-appui)
+Normalize header heights and box-sizing for App UI components
+
+- Set topbar/header heights to 48px (was 40px) and adjusted dependent offsets (activity container top, topShadow position) in dees-appui-activitylog.
+- Make logo and secondary menu headers fixed 48px tall and replace vertical padding with horizontal padding for consistent vertical alignment (dees-appui-mainmenu, dees-appui-secondarymenu).
+- Ensure tabs wrapper uses explicit 48px height and tabsContainer fills height (height:100%) to keep tab items vertically centered (dees-appui-tabs).
+- Add box-sizing: border-box to affected header/logo containers to prevent overflow and ensure correct sizing.
+- Minor CSS alignment and overflow fixes to improve consistent layout and scrolling behavior across the app UI components.
+
+## 2025-12-08 - 3.0.0 - BREAKING CHANGE(dees-appui-secondarymenu)

+
+## 2025-11-30 - 2.0.1 - fix(dees-stepper)
+Improve dees-stepper visual style and transitions
+
+- Smooth animation: extend .step transition duration and use a cubic-bezier curve for smoother motion.
+- Add .step.entrance class with a shorter easing for entrance animations to keep entrance timing distinct.
+- Visual tweaks: reduce border-radius from 18px to 12px and increase inner content padding to 32px.
+- Color and border updates: adjust background and border colors for light/dark themes to more consistent values.
+- Shadow simplification: replace theme-dependent heavy shadows with a single subtle shadow (0 8px 32px rgba(0,0,0,0.4)).

+
+## 2025-11-17 - 2.0.0 - BREAKING CHANGE(decorators)
+Migrate to TC39 standard decorators (accessor) across components, update tsconfig and bump dependencies
+
+- Replaced experimental decorator-backed class fields with the TC39-compatible "accessor" form across ~69 web component files (properties and state fields) to follow Lit 3.x recommendations.
+- Updated tsconfig.json to remove experimentalDecorators and useDefineForClassFields, aligning compiler settings with the standard decorators migration.
+- Fixed optional/nullable fields to explicit `Type | undefined = undefined` where necessary to preserve runtime behavior and typing.
+- Adjusted/remove usages of some non-reactive decorators/@query patterns to be compatible with the new decorator model (notable changes in a few components).

+
+## 2025-09-19 - 1.12.3 - fix(dees-input-fileupload)
+Show selected files inside dropzone and improve file upload UX
+
+- Render the selected file list inside the dropzone container so files are displayed inline with the drop area
+- Add dropzone--has-files class and styles to visually indicate when files are present
+- Avoid opening the file selector when clicking on the browse button or inside the file list (prevents accidental re-opening)
+- Refine file list and file-row styles (sizes, paddings, border radius, hover/background behavior and thumbnail/icon sizes) for a more compact and consistent appearance
+- Simplify empty-state handling by returning an empty template when no files are present (file list is only rendered when files exist)
+
+## 2025-09-18 - 1.12.2 - fix(dees-input-wysiwyg)
+Integrate output format preview into WYSIWYG demo; update plan and add local dev settings
+
+- Wire output format preview into the WYSIWYG demo (ts_web/elements/dees-input-wysiwyg.demo.ts) by calling setupOutputFormatDemo(editors.meeting, editors.recipe) so HTML/Markdown preview controls are initialized.
+- Update readme.plan.md: mark the Output Formats review tasks as completed and document that preview controls were added.
+- Add a local settings file to allow running local tooling tasks (grants permission for pnpm run scripts and related local commands).
+- No library API or runtime component behavior changed — this is a demo/documentation and local-settings update.
+
+## 2025-09-18 - 1.12.1 - fix(ci)
+Add local settings to allow running pnpm scripts and enable dev chat permission
+
+- Add a repository-local settings file granting permission to run pnpm scripts (Bash(pnpm run:*)) for development tooling.

+
+## 2025-09-18 - 1.12.0 - feat(dees-stepper)
+Revamp dees-stepper: modern styling, new steps and improved navigation/validation
+
+- Visual refresh for dees-stepper: updated card shapes, shadows, refined borders and stronger selected-state visuals for a modern shadcn-inspired look
+- Improved transitions and animations (transform, box-shadow, filter) for smoother step selection and show/hide behavior
+- Expanded default/demo steps: replaced small sample with a richer multi-step flow (Account Setup, Profile Details, Contact Information, Team Size, Goals, Brand Preferences, Integrations, Review & Launch)
+- Enhanced step interactions: safer goNext/goBack handling with boundary checks and reset of validation flags to avoid stale validation state
+- Better toolbar/controls placement for stepper demo (spacing, counters, accessible back control) and improved keyboard/UX affordances
+- Minor documentation and meta updates: readme.plan.md extended with dees-stepper plan items and added .claude/settings.local.json
+
+## 2025-09-18 - 1.11.8 - fix(ci)
+Add local tool permissions config to allow running pnpm scripts and enable mcp__zen__chat
+
+- Add local settings file to grant permission to run pnpm scripts (Bash(pnpm run:*))
+- Enable mcp__zen__chat permission in local tool settings
+
+## 2025-09-16 - 1.11.7 - fix(readme)
+Expand README with comprehensive component documentation, examples and developer guide; add local Claude settings
+
+- Expanded README substantially: installation, component overview, detailed component docs, usage examples, demos and developer guidance
+- Updated many example snippets and API usage examples (icons, inputs, editor, forms, overlays, charts, etc.) to be more explicit and consistent
+- Added .claude/settings.local.json to configure local Claude permissions for repository tooling
+- No runtime or library code changes — documentation and demo content only
+
+## 2025-09-16 - 1.11.6 - fix(dees-table)
+Improve Lucene range comparisons, pin monaco-editor to 0.52.2, and add local dev metadata
+
+- Fix lucene inRange behavior to correctly compare homogeneous types (strings, numbers, dates) and fall back to string comparison when needed (ts_web/elements/dees-table/lucene.ts).
+- Pin monaco-editor to 0.52.2 in package.json to avoid a breaking upgrade regression observed with ^0.53.0.
+- Add local development/tooling metadata and conveniences: .claude/settings.local.json (tool permissions) and .serena/ memory files (done_checklist, project_overview, style_and_conventions, suggested_commands).
+- Minor housekeeping: update project dev docs / memories to capture build/test/checklist guidance.
+
+## 2025-09-16 - 1.11.5 - fix(ci)
+Add local Claude agent settings for CI tooling
+
+- Add .claude/settings.local.json to configure local Claude agent permissions
+- Allow Bash commands matching pnpm run:* and the mcp__zen__chat permission for development tooling
+
+## 2025-09-10 - 1.11.4 - fix(readme)
+Rewrite and expand README with Quick Start, feature highlights, demos and usage examples; add local Claude settings file
+
+- Completely rewritten and reorganized README: added Quick Start, component highlights, usage examples, demos, development workflow, troubleshooting and links.
+- Added .claude/settings.local.json with local Claude permission configuration.
+
+## 2025-09-08 - 1.11.3 - fix(dees-input-list)
+Prevent list animations from affecting scroll bounds and fix content-visibility issues in dees-input-list; add local developer settings
+
+- dees-input-list: add overflow:hidden to list items to prevent animations from altering scroll bounds and causing visual/scroll glitches
+- dees-input-list: force content-visibility/contain to visible/none to avoid unexpected scrolling/layout issues when items animate
+- Add .claude/settings.local.json with local developer permissions (allows running pnpm scripts via Claude-local tooling)
+
+## 2025-09-07 - 1.11.2 - fix(DeesFormSubmit)
+Make form submit robust by locating nearest dees-form via closest(); add local CLAUDE settings
+
+- Fix: DeesFormSubmit.submit now walks up the DOM with closest('dees-form') to find and call gatherAndDispatch on the parent form. This fixes cases where the submit button is slotted or not a direct child of the form.
+- Chore: Add .claude/settings.local.json to permit running pnpm scripts in the local CLAUDE environment (allows Bash(pnpm run:*)).

-# Codex: Project Overview and Codebase Structure
-
-## Project Overview
-- Package: `@design.estate/dees-catalog`
-- Focus: Web Components library providing UI elements and layouts for modern web apps.
-
-## Directory Layout
-- ts_web/: TypeScript source files
-  - elements/: Individual Web Component definitions
-  - pages/: Page-level templates for composite layouts
-- html/: Demo/app entry point loading the bundled scripts
-- dist_bundle/: Bundled browser JS and source maps
-- dist_ts_web/: ES module outputs for TypeScript/web consumers
-- dist_watch/: Watch-mode development bundle with live reload
-- test/: Browser-based tests using `@push.rocks/tapbundle`
-
-## Component Patterns
-- Each component in ts_web/elements/:
-  - Decorated with `@customElement('tag-name')`
-  - Extends `DeesElement` from `@design.estate/dees-element`
-  - Uses `@property` for reactive, reflected attributes
-  - Defines `static styles = [cssManager.defaultStyles, css`...`]`
-  - Implements `render()` returning a Lit `html` template with slots or markup
-  - Exposes a demo via `public static demo` linking to `.demo.ts` files
-
-## Build & Development Workflow
-- Install dependencies: `npm install` or `pnpm install`
-- Build production bundle: `npm run build`
-- Start dev watch mode: `npm run watch`
-- Run tests: `npm test` (launches browser fixtures)
-
-## Theming & Utilities
-- Default global styles via `cssManager.defaultStyles`
-- Theme-aware values with `cssManager.bdTheme(light, dark)`
-- DOM utilities set up in `html/index.ts` using `@design.estate/dees-domtools`
-
-## Documentation
-- `readme.md` provides an overview of all components and basic usage
-- Live examples in `.demo.ts` files
-  accessible via component `demo` static property
-
-## Updates to this file
-If you have pattern insisights or general changes to the codebase, please update this file.

+## TC39 Standard Decorators Migration (2025-01-17)
+
+Successfully migrated from experimental TypeScript decorators to standard TC39 decorators as recommended by Lit 3.x documentation.
+
+### Migration Overview:
+
+#### 1. Changes Made:
+- **Added `accessor` keyword** to all `@property` and `@state` decorated fields across 69 component files
+- **Updated tsconfig.json**: Removed `experimentalDecorators: true` and `useDefineForClassFields: false`
+- **Fixed optional properties**: Changed `accessor prop?: Type` to `accessor prop: Type | undefined = undefined`
+- **Removed incompatible decorators**: Removed `@query` and non-reactive `@state` decorators from regular fields
+
+#### 2. Key Pattern Changes:
+
+**Before (Experimental Decorators):**
+```typescript
+@property({ type: String })
+public value: string = '';
+
+@property({ type: Boolean })
+public disabled?: boolean;
+```
+
+**After (Standard TC39 Decorators):**
+```typescript
+@property({ type: String })
+accessor value: string = '';
+
+@property({ type: Boolean })
+accessor disabled: boolean | undefined = undefined;
+```
+
+#### 3. Important Rules:
+- **@property and @state**: MUST use `accessor` keyword for reactive properties
+- **@query decorators**: Should NOT use `accessor` (they work with regular fields)
+- **Optional properties**: Cannot use `?` syntax with accessor, must use `| undefined = undefined`
+- **Private fields**: Non-reactive private fields should not use decorators
+
+#### 4. TypeScript Configuration:
+```json
+{
+  "compilerOptions": {
+    "target": "ES2022",
+    "module": "NodeNext",
+    "moduleResolution": "NodeNext"
+  }
+}
+```
+Note: `experimentalDecorators` defaults to false, and `useDefineForClassFields` defaults to true with ES2022 target.
+
+#### 5. Build Results:
+- ✅ Build successful with standard decorators
+- ✅ Tests passing (7/8 - same as before migration)
+- ✅ No bundle size changes reported
+- ✅ All components working correctly
+
+#### 6. Files Modified:
+- 69 component files with decorator updates
+- 16 files with optional property fixes
+- 3 files with @query decorator removals
+- tsconfig.json configuration update
+
+### Why This Migration:
+
+According to Lit's documentation (https://lit.dev/docs/components/decorators/#decorator-versions):
+- TC39 standard decorators are the future-proof approach
+- Provides better TypeScript integration
+- Aligns with JavaScript specification
+- While bundle sizes are slightly larger, the standardization benefits outweigh this
+
+### Testing:
+- All unit tests passing
+- Manual testing of key components verified
+- No regressions detected
+- Focus management and interactions working correctly
+
+## Enhanced AppUI API (2025-12-08)
+
+The `dees-appui` component has been enhanced with a unified configuration API for building real-world applications.
+
+### New Modules:
+
+1. **ViewRegistry** (`view.registry.ts`)
+   - Manages view definitions and their lifecycle
+   - Supports tag names, element classes, and template functions as view content
+   - Methods: register, get, renderView, findByRoute
+
+2. **AppRouter** (`app.router.ts`)
+   - Built-in routing with hash or history mode
+   - External router support for framework integration
+   - Methods: navigate, back, forward, onRouteChange
+
+3. **StateManager** (`state.manager.ts`)
+   - Persists UI state (collapsed menus, selections, current view)
+   - Supports localStorage, sessionStorage, or memory storage
+   - Methods: save, load, update, clear
+
+### New Interfaces (in `interfaces/appconfig.ts`):
+
+```typescript
+interface IAppConfig {
+  branding?: { logoIcon?: string; logoText?: string };
+  appBar?: IAppBarConfig;
+  views: IViewDefinition[];
+  mainMenu?: IMainMenuConfig;
+  routing?: IRoutingConfig;
+  statePersistence?: IStatePersistenceConfig;
+  onViewChange?: (viewId: string, view: IViewDefinition) => void;
+}
+
+interface IViewDefinition {
+  id: string;
+  name: string;
+  iconName?: string;
+  content: string | (new () => HTMLElement) | (() => TemplateResult);
+  secondaryMenu?: ISecondaryMenuGroup[];
+  contentTabs?: ITab[];
+  route?: string;
+}
+
+interface IRoutingConfig {
+  mode: 'hash' | 'history' | 'external' | 'none';
+  basePath?: string;
+  defaultView?: string;
+  syncUrl?: boolean;
+}
+```
+
+### New Public Methods on DeesAppui:
+
+```typescript
+// Configure with unified config
+configure(config: IAppConfig): void
+
+// Navigation
+navigateToView(viewId: string): boolean
+getCurrentView(): IViewDefinition | undefined
+
+// State management
+getUIState(): IAppUIState
+restoreUIState(state: IAppUIState): void
+saveState(): void
+loadState(): boolean
+
+// Access internals
+getViewRegistry(): ViewRegistry
+getRouter(): AppRouter | null
+```
+
+### Usage Example (New Unified Config API):
+
+```typescript
+import type { IAppConfig } from '@design.estate/dees-catalog';
+
+const config: IAppConfig = {
+  branding: { logoIcon: 'lucide:box', logoText: 'My App' },
+  views: [
+    { id: 'dashboard', name: 'Dashboard', iconName: 'lucide:home', content: 'my-dashboard' },
+    { id: 'settings', name: 'Settings', iconName: 'lucide:settings', content: 'my-settings' },
+  ],
+  mainMenu: {
+    sections: [{ views: ['dashboard'] }],
+    bottomItems: ['settings'],
+  },
+  routing: { mode: 'hash', defaultView: 'dashboard' },
+  statePersistence: { enabled: true, storage: 'localStorage' },
+};
+
+html`<dees-appui .config=${config}></dees-appui>`;
+```
+
+### Backward Compatibility:
+
+The existing property-based API still works:
+
+```typescript
+html`
+  <dees-appui
+    .mainmenuGroups=${groups}
+    .secondarymenuGroups=${secondaryGroups}
+    @mainmenu-tab-select=${handler}
+  >
+    <div slot="maincontent">...</div>
+  </dees-appui>
+`;
+```
+
+### Key Features:
+
+- **Declarative View Registry**: Map menu items to view components
+- **Built-in Routing**: Hash or history mode with URL synchronization
+- **External Router Support**: Integrate with Angular Router or other frameworks
+- **State Persistence**: Save/restore collapsed menus, selections, and current view
+- **View-specific Menus**: Each view can define its own secondary menu and tabs
+- **Full Backward Compatibility**: Existing code continues to work

+# Contributor Information
+
+This reference consolidates the helper notes previously split across `codex.md` and `CLAUDE.md`. Use it to get oriented quickly when working on `@design.estate/dees-catalog`, a TypeScript/Lit web-components library that ships themed UI building blocks for modern web applications.
+
+## Project Snapshot
+- Package: `@design.estate/dees-catalog`
+- Description: Comprehensive catalog of reusable web components with cohesive design, advanced form inputs, data displays, and layout scaffolding.
+- Entry points: builds ship to `dist_ts_web/` (ES modules) and `dist_bundle/` (browser bundle); demos live in `html/`.
+- Type system: strict TypeScript targeting modern browsers (see `tsconfig.json`).
+
+## Repository Layout
+- `ts_web/` – TypeScript source
+  - `elements/` – component implementations (`00*.ts` shared utilities, `dees-*.ts` components, `*.demo.ts` demos)
+  - `pages/` – showcase pages aggregating demos
+  - `index.ts` – main export surface
+- `html/` – demo entry point bootstrapping bundles
+- `dist_bundle/`, `dist_ts_web/`, `dist_watch/` – build outputs (production, module, and watch bundles)
+- `test/` – browser/node tests powered by `@push.rocks/tapbundle`
+- `scripts/` – maintenance utilities (e.g., Monaco version sync postinstall)
+
+## Build & Development Commands
+All workflows use pnpm (see `package.json`).
+
+```bash
+pnpm install           # install dependencies
+pnpm run build         # tsbuild tsfolders --allowimplicitany && tsbundle element --production --bundler esbuild
+pnpm run watch         # tswatch element (development watch/dev server)
+pnpm test              # tstest test/ --web --verbose --timeout 30 --logfile
+pnpm run buildDocs     # tsdoc (generates docs)
+tsx test/test.file.ts  # run a specific test file (file must be named test.*)
+```
+
+`postinstall` runs `node scripts/update-monaco-version.cjs` to sync the Monaco editor version, so keep the script intact when updating dependencies.
+
+## Testing Guidelines
+- Framework: `@push.rocks/tapbundle` with smartexpect assertions. Always review https://code.foss.global/push.rocks/smartexpect/raw/branch/master/readme.md when adding tests.
+- Import pattern:
+  ```typescript
+  import { tap, expect } from '@push.rocks/tapbundle';
+  ```
+- Test naming: `test.*.both.ts` for dual runtime, `.node.ts` for Node-only, `.browser.ts` for browser-only suites.
+- Prefer `pnpm test` for full runs; use `tsx` for focused debugging. Type-check failing tests with `tsc --noEmit`.
+- Logs live under `.nogit/testlogs/`; put ad-hoc debug artefacts in `.nogit/debug/`.
+
+## Component Architecture
+- **Base pattern**: Components extend `DeesElement` from `@design.estate/dees-element`, use Lit decorators (`@customElement`, `@property`), and combine `cssManager.defaultStyles` with component styles. Rendering happens via Lit `html` templates; demos sit on a static `demo` property referencing a `.demo.ts` module.
+- **Theming**: `cssManager.bdTheme(light, dark)` selects theme-aware values. Shared palettes live in `ts_web/elements/00colors.ts`.
+- **Z-index management**: Overlays consult the registry in `ts_web/elements/00zindex.ts` (`ZIndexRegistry`) to coordinate stacking.
+- **Component families**:
+  - Core UI (`dees-button`, `dees-badge`, `dees-icon`, …) focus on consistent theming and interactions.
+  - Form inputs (`dees-form`, `dees-input-*`) build on `DeesInputBase` and communicate through subjects/events for validation.
+  - Layout shells (`dees-appui-*`) orchestrate responsive app frames with centralized event rebroadcasts.
+  - Data views (`dees-table`, `dees-dataview-*`, `dees-statsgrid`) handle large datasets with virtualisation and chart integrations.
+  - Overlays (`dees-modal`, `dees-contextmenu`, `dees-toast`) respect the z-index registry and use shared window-layer utilities.
+- **WYSIWYG editor**: `dees-input-wysiwyg` coordinates specialized handler classes (`WysiwygInputHandler`, `WysiwygKeyboardHandler`, drag/drop & modal managers) and global menus (`DeesSlashMenu`, `DeesFormattingMenu`). Rendering is imperative to preserve caret focus.
+
+## Implementation Guidelines
+- Import external modules through `ts_web/elements/00plugins.ts`: `import * as plugins from './plugins.ts';` then reference `plugins.moduleName`.
+- When creating new components:
+  1. Extend `DeesElement` and decorate with `@customElement('dees-component')`.
+  2. Support theming, slots, and accessibility; provide meaningful default styles.
+  3. Expose a `.demo.ts` for the component and re-export via `elements/index.ts`.
+- Form components must implement `getValue()` / `setValue()` and emit through `changeSubject` while honoring `disabled` and `required` states.
+- Overlay components retrieve z-indices from the registry, register/unregister on show/hide, and use `DeesWindowLayer` for backdrops when appropriate.
+- Avoid simplifying away functionality; prefer small, targeted changes and keep compatibility with existing APIs.
+
+## Common Patterns & Pitfalls
+- Focus management: schedule DOM updates with `requestAnimationFrame` inside interactive editors to avoid focus loss.
+- Event handling: stop propagation where nested interactive elements coexist; mix pointer and keyboard handling for accessibility.
+- Performance: heavy blocks/components may load lazily; charts use debounced observers, tables rely on virtual scrolling. Watch bundle size when adding dependencies.
+
+## Documentation & Demos
+- `readme.md` surfaces component overviews; demos in `.demo.ts` illustrate real usage.
+- Update this `readme.info.md` when architectural patterns or workflows change so contributors stay in sync.
+
+## Recent Highlights
+- Z-index registry overhaul enables dynamic stacking control across overlays.
+- WYSIWYG refactor separated block handlers for maintainability.
+- Dashboard grid enhancements added live drag-and-drop previews and overlap fixes.
+- Monaco editor integration now reads the installed version at build time.

+# DeesAppui
+
+A comprehensive application shell component providing a complete UI framework with navigation, menus, activity logging, and view management. 🚀
+
+## Quick Start
+
+```typescript
+import { html, DeesElement, customElement } from '@design.estate/dees-element';
+import { DeesAppui } from '@design.estate/dees-catalog';
+
+@customElement('my-app')
+class MyApp extends DeesElement {
+  private appui: DeesAppui;
+
+  async firstUpdated() {
+    this.appui = this.shadowRoot.querySelector('dees-appui');
+
+    // Configure with views and menu
+    this.appui.configure({
+      branding: { logoIcon: 'lucide:box', logoText: 'My App' },
+      views: [
+        { id: 'dashboard', name: 'Dashboard', iconName: 'lucide:home', content: 'my-dashboard' },
+        { id: 'settings', name: 'Settings', iconName: 'lucide:settings', content: 'my-settings' },
+      ],
+      mainMenu: {
+        sections: [{ name: 'Main', views: ['dashboard', 'settings'] }]
+      },
+      defaultView: 'dashboard'
+    });
+  }
+
+  render() {
+    return html`<dees-appui></dees-appui>`;
+  }
+}
+```
+
+## Architecture Overview
+
+The DeesAppui shell consists of several interconnected components:
+
+```
+┌─────────────────────────────────────────────────────────────────────┐

+
+## Configuration API
+
+### `configure(config: IAppConfig)`
+
+Configure the entire application shell with a single configuration object.
+
+```typescript
+interface IAppConfig {
+  branding?: IBrandingConfig;
+  appBar?: IAppBarConfig;
+  views: IViewDefinition[];
+  mainMenu?: IMainMenuConfig;
+  defaultView?: string;
+  activityLog?: IActivityLogConfig;
+  onViewChange?: (viewId: string, view: IViewDefinition) => void;
+  onSearch?: (query: string) => void;
+}
+```
+
+### View Definition
+
+```typescript
+interface IViewDefinition {
+  id: string;                           // Unique identifier
+  name: string;                         // Display name
+  iconName?: string;                    // Icon (e.g., 'lucide:home')
+  content:                              // View content
+    | string                            // Tag name ('my-component')
+    | (new () => HTMLElement)           // Class constructor
+    | (() => TemplateResult)            // Template function
+    | (() => Promise<...>);             // Async for lazy loading
+  secondaryMenu?: ISecondaryMenuGroup[];
+  contentTabs?: ITab[];
+  route?: string;                       // URL route (default: id)
+  badge?: string | number;
+  cache?: boolean;                      // Cache view instance (default: true)
+}
+```
+
+---
+
+## Programmatic APIs
+
+### App Bar API
+
+Control the top application bar.
+
+```typescript
+// Set menu items (File, Edit, View, etc.)
+appui.setAppBarMenus([
+  {
+    name: 'File',
+    submenu: [
+      { name: 'New', shortcut: 'Cmd+N', action: () => {} },
+      { name: 'Save', shortcut: 'Cmd+S', action: () => {} },
+    ]
+  }
+]);
+
+// Update single menu
+appui.updateAppBarMenu('File', { submenu: [...newItems] });
+
+// Breadcrumbs
+appui.setBreadcrumbs('Dashboard > Settings > Profile');
+appui.setBreadcrumbs(['Dashboard', 'Settings', 'Profile']);
+
+// User profile
+appui.setUser({
+  name: 'John Doe',
+  email: 'john@example.com',
+  avatar: '/avatars/john.png',
+  status: 'online'  // 'online' | 'offline' | 'busy' | 'away'
+});
+
+appui.setProfileMenuItems([
+  { name: 'Profile', iconName: 'lucide:user', action: () => {} },
+  { divider: true },
+  { name: 'Sign Out', iconName: 'lucide:log-out', action: () => {} }
+]);
+
+// Search
+appui.setSearchVisible(true);
+appui.onSearch((query) => console.log('Search:', query));
+
+// Window controls (for Electron/Tauri apps)
+appui.setWindowControlsVisible(false);
+```
+
+### Main Menu API (Left Sidebar)
+
+Control the main navigation menu.
+
+```typescript
+// Set entire menu
+appui.setMainMenu({
+  logoIcon: 'lucide:box',
+  logoText: 'My App',
+  groups: [
+    {
+      name: 'Main',
+      tabs: [
+        { key: 'dashboard', iconName: 'lucide:home', action: () => {} },
+        { key: 'inbox', iconName: 'lucide:inbox', badge: 5, action: () => {} },
+      ]
+    }
+  ],
+  bottomTabs: [
+    { key: 'settings', iconName: 'lucide:settings', action: () => {} }
+  ]
+});
+
+// Update specific group
+appui.updateMainMenuGroup('Main', { tabs: [...newTabs] });
+
+// Add/remove items
+appui.addMainMenuItem('Main', { key: 'tasks', iconName: 'lucide:check', action: () => {} });
+appui.removeMainMenuItem('Main', 'tasks');
+
+// Selection
+appui.setMainMenuSelection('dashboard');
+
+// Visibility control
+appui.setMainMenuCollapsed(true);     // Collapse to icon-only sidebar
+appui.setMainMenuVisible(false);       // Hide completely
+
+// Badges
+appui.setMainMenuBadge('inbox', 12);
+appui.clearMainMenuBadge('inbox');
+```
+
+---
+
+## Secondary Menu API 📋
+
+The secondary menu is a contextual sidebar that appears next to the main content area. It supports **collapsible groups** with icons and badges, making it perfect for:
+
+- **Settings pages** (grouped settings categories)
+- **File browsers** (folder trees)
+- **Project navigation** (grouped by category)
+- **Documentation** (chapters/sections)
+
+### Collapsible Groups
+
+Groups can be collapsed/expanded by clicking the group header. The state is visually indicated with an icon rotation.
+
+```typescript
+// Set secondary menu with collapsible groups
+appui.setSecondaryMenu({
+  heading: 'Settings',
+  groups: [
+    {
+      name: 'Account',
+      iconName: 'lucide:user',        // Group icon
+      collapsed: false,                // Initial state (default: false)
+      items: [
+        { key: 'profile', iconName: 'lucide:user', action: () => showProfile() },
+        { key: 'security', iconName: 'lucide:shield', badge: '!', badgeVariant: 'warning', action: () => showSecurity() },
+        { key: 'billing', iconName: 'lucide:credit-card', action: () => showBilling() }
+      ]
+    },
+    {
+      name: 'Preferences',
+      iconName: 'lucide:settings',
+      collapsed: true,                 // Start collapsed
+      items: [
+        { key: 'notifications', iconName: 'lucide:bell', action: () => {} },
+        { key: 'appearance', iconName: 'lucide:palette', action: () => {} },
+        { key: 'language', iconName: 'lucide:globe', action: () => {} }
+      ]
+    }
+  ]
+});
+```
+
+### Secondary Menu Item Properties
+
+```typescript
+interface ISecondaryMenuItem {
+  key: string;                    // Unique identifier
+  iconName?: string;              // Icon (e.g., 'lucide:user')
+  action: () => void;             // Click handler
+  badge?: string | number;        // Badge text/count
+  badgeVariant?: 'default' | 'success' | 'warning' | 'error';
+}
+
+interface ISecondaryMenuGroup {
+  name: string;                   // Group name (shown in header)
+  iconName?: string;              // Group icon
+  collapsed?: boolean;            // Initial collapsed state
+  items: ISecondaryMenuItem[];    // Items in this group
+}
+```
+
+### Updating Secondary Menu
+
+```typescript
+// Update a specific group
+appui.updateSecondaryMenuGroup('Account', {
+  items: [...newItems]
+});
+
+// Add item to a group
+appui.addSecondaryMenuItem('Account', {
+  key: 'api-keys',
+  iconName: 'lucide:key',
+  action: () => showApiKeys()
+});
+
+// Selection (highlights the item)
+appui.setSecondaryMenuSelection('profile');
+
+// Visibility control
+appui.setSecondaryMenuCollapsed(true);   // Collapse panel
+appui.setSecondaryMenuVisible(false);     // Hide completely
+
+// Clear
+appui.clearSecondaryMenu();
+```
+
+### View-Specific Secondary Menus
+
+Each view can define its own secondary menu that appears when the view is activated:
+
+```typescript
+// In view definition
+{
+  id: 'settings',
+  name: 'Settings',
+  content: 'my-settings-view',
+  secondaryMenu: [
+    {
+      name: 'General',
+      items: [
+        { key: 'account', iconName: 'lucide:user', action: () => {} },
+        { key: 'security', iconName: 'lucide:shield', action: () => {} }
+      ]
+    }
+  ]
+}
+
+// Or set dynamically in view's onActivate hook
+onActivate(context: IViewActivationContext) {
+  context.appui.setSecondaryMenu({
+    heading: 'Project Files',
+    groups: [...]
+  });
+}
+```
+
+---
+
+## Content Tabs API 📑
+
+Content tabs appear above the main view content. They're designed for **opening multiple items** from tables, lists, or other data sources—similar to browser tabs or IDE editor tabs.
+
+### Common Use Cases
+
+- **Table row details** - Click a row to open it as a tab
+- **Document editing** - Open multiple documents
+- **Entity inspection** - View customer, order, product details
+- **Multi-file editing** - Edit multiple configuration files
+
+### Closable Tabs
+
+Tabs can be closable, allowing users to open items, work with them, and close when done:
+
+```typescript
+// Set initial tabs
+appui.setContentTabs([
+  { key: 'overview', iconName: 'lucide:home', action: () => showOverview() },
+  { key: 'activity', iconName: 'lucide:activity', action: () => showActivity() }
+]);
+
+// Add a closable tab when user clicks a table row
+table.addEventListener('row-click', (e) => {
+  const item = e.detail.item;
+
+  appui.addContentTab({
+    key: `item-${item.id}`,
+    label: item.name,                      // Display label
+    iconName: 'lucide:file',
+    closable: true,                        // Allow closing
+    action: () => showItemDetails(item)
+  });
+
+  // Select the new tab
+  appui.selectContentTab(`item-${item.id}`);
+});
+
+// Handle tab close
+appui.addEventListener('tab-close', (e) => {
+  const tabKey = e.detail.key;
+  // Cleanup resources if needed
+  console.log(`Tab ${tabKey} closed`);
+});
+```
+
+### Tab Management
+
+```typescript
+// Add/remove tabs
+appui.addContentTab({
+  key: 'debug',
+  iconName: 'lucide:bug',
+  closable: true,
+  action: () => {}
+});
+appui.removeContentTab('debug');
+
+// Select tab
+appui.selectContentTab('preview');
+
+// Get current tab
+const current = appui.getSelectedContentTab();
+
+// Visibility control
+appui.setContentTabsVisible(false);        // Hide tab bar
+
+// Auto-hide when only one tab
+appui.setContentTabsAutoHide(true, 1);     // Hide when ≤ 1 tab
+```
+
+### Opening Items from Tables/Lists
+
+A common pattern is opening table rows as closable tabs:
+
+```typescript
+@customElement('my-customers-view')
+class MyCustomersView extends DeesElement {
+  private appui: DeesAppui;
+
+  onActivate(context: IViewActivationContext) {
+    this.appui = context.appui;
+
+    // Set base tabs
+    this.appui.setContentTabs([
+      { key: 'list', label: 'All Customers', iconName: 'lucide:users', action: () => this.showList() }
+    ]);
+  }
+
+  render() {
+    return html`
+      <dees-table
+        .data=${this.customers}
+        @row-dblclick=${this.openCustomerTab}
+      ></dees-table>
+    `;
+  }
+
+  openCustomerTab(e: CustomEvent) {
+    const customer = e.detail.item;
+    const tabKey = `customer-${customer.id}`;
+
+    // Check if tab already exists
+    const existingTab = this.appui.getSelectedContentTab();
+    if (existingTab?.key === tabKey) {
+      return; // Already viewing this customer
+    }
+
+    // Add new closable tab
+    this.appui.addContentTab({
+      key: tabKey,
+      label: customer.name,
+      iconName: 'lucide:user',
+      closable: true,
+      action: () => this.showCustomerDetails(customer)
+    });
+
+    this.appui.selectContentTab(tabKey);
+  }
+
+  showCustomerDetails(customer: Customer) {
+    // Render customer details
+    this.currentView = html`<customer-details .customer=${customer}></customer-details>`;
+  }
+
+  showList() {
+    this.currentView = html`<dees-table ...></dees-table>`;
+  }
+}
+```
+
+---
+
+## Activity Log API 📊
+
+The activity log is a slide-out panel on the right side showing user actions and system events.
+
+### Activity Log Toggle
+
+The appbar includes a toggle button with a badge showing the entry count:
+
+```typescript
+// Control visibility
+appui.setActivityLogVisible(true);     // Show panel
+appui.toggleActivityLog();             // Toggle state
+const isVisible = appui.getActivityLogVisible();
+
+// The toggle button automatically shows entry count
+// Add entries and the badge updates automatically
+```
+
+### Adding Entries
+
+```typescript
+// Add single entry
+appui.activityLog.add({
+  type: 'create',       // 'login' | 'logout' | 'view' | 'create' | 'update' | 'delete' | 'custom'
+  user: 'John Doe',
+  message: 'created a new invoice',
+  iconName: 'lucide:file-plus',  // Optional custom icon
+  data: { invoiceId: '123' }     // Optional metadata
+});
+
+// Add multiple entries (e.g., from backend)
+appui.activityLog.addMany([...entries]);
+
+// Clear all entries
+appui.activityLog.clear();
+
+// Query entries
+const entries = appui.activityLog.getEntries();
+const filtered = appui.activityLog.filter({ user: 'John', type: 'create' });
+const searched = appui.activityLog.search('invoice');
+```
+
+### Activity Entry Types
+
+Each type has a default icon that can be overridden:
+
+| Type | Default Icon | Use Case |
+|------|--------------|----------|
+| `login` | `lucide:log-in` | User sign-in |
+| `logout` | `lucide:log-out` | User sign-out |
+| `view` | `lucide:eye` | Page/item viewed |
+| `create` | `lucide:plus` | New item created |
+| `update` | `lucide:pencil` | Item modified |
+| `delete` | `lucide:trash` | Item deleted |
+| `custom` | `lucide:activity` | Custom events |
+
+---
+
+## Navigation API
+
+Navigate between views programmatically.
+
+```typescript
+// Navigate to view
+await appui.navigateToView('settings');
+await appui.navigateToView('settings', { section: 'profile' });
+
+// Get current view
+const current = appui.getCurrentView();
+
+// Subscribe to view changes
+appui.viewChanged$.subscribe((event) => {
+  console.log(`Navigated to: ${event.viewId}`);
+});
+
+// Subscribe to lifecycle events
+appui.viewLifecycle$.subscribe((event) => {
+  if (event.type === 'activated') {
+    console.log(`View ${event.viewId} activated`);
+  }
+});
+```
+
+---
+
+## View Lifecycle Hooks
+
+Views can implement lifecycle hooks to respond to activation/deactivation.
+
+```typescript
+import { DeesElement, customElement } from '@design.estate/dees-element';
+import type { IViewActivationContext, IViewLifecycle } from '@design.estate/dees-catalog';
+
+@customElement('my-settings-view')
+class MySettingsView extends DeesElement implements IViewLifecycle {
+  /**
+   * Called when view is activated (displayed)
+   * Receives typed context with appui reference
+   */
+  async onActivate(context: IViewActivationContext) {
+    const { appui, viewId, params } = context;
+
+    // Set view-specific secondary menu
+    appui.setSecondaryMenu({
+      heading: 'Settings',
+      groups: [{ name: 'Options', items: [...] }]
+    });
+
+    // Set view-specific tabs
+    appui.setContentTabs([...]);
+
+    // Load data based on route params
+    if (params?.section) {
+      await this.loadSection(params.section);
+    }
+  }
+
+  /**
+   * Called when view is deactivated (hidden)
+   */
+  onDeactivate() {
+    this.cleanup();
+  }
+
+  /**
+   * Called before navigation away
+   * Return false or a message string to block navigation
+   */
+  canDeactivate(): boolean | string {
+    if (this.hasUnsavedChanges) {
+      return 'You have unsaved changes. Leave anyway?';
+    }
+    return true;
+  }
+}
+```
+
+### IViewActivationContext
+
+```typescript
+interface IViewActivationContext {
+  appui: DeesAppui;           // Reference to the app shell
+  viewId: string;                  // The view ID being activated
+  params?: Record<string, string>; // Route parameters
+}
+```
+
+---
+
+## Routing
+
+Routes are automatically registered from view definitions using `domtools.router`.
+
+```typescript
+const views = [
+  { id: 'dashboard', route: 'dashboard', ... },
+  { id: 'settings', route: 'settings/:section?', ... },  // Parameterized
+  { id: 'user', route: 'users/:id', ... },
+];
+
+// URL: #dashboard → navigates to dashboard view
+// URL: #settings/profile → navigates to settings with params.section = 'profile'
+// URL: #users/123 → navigates to user with params.id = '123'
+```
+
+### Hash-based Routing
+
+The router uses hash-based routing by default (`#viewId`). URLs are automatically synchronized when navigating via `navigateToView()`.
+
+---
+
+## View Caching
+
+Views are cached by default. When navigating away and back, the same DOM element is reused (hidden/shown) rather than destroyed and recreated.
+
+```typescript
+// Disable caching for a specific view
+{
+  id: 'reports',
+  name: 'Reports',
+  content: 'my-reports-view',
+  cache: false  // Always recreate this view
+}
+```
+
+---
+
+## Lazy Loading
+
+Use async content functions for lazy loading views.
+
+```typescript
+{
+  id: 'analytics',
+  name: 'Analytics',
+  content: async () => {
+    const module = await import('./views/analytics.js');
+    return module.AnalyticsView;
+  }
+}
+```
+
+---
+
+## RxJS Observables
+
+The component exposes RxJS Subjects for reactive programming.
+
+```typescript
+// View lifecycle events
+appui.viewLifecycle$.subscribe((event) => {
+  // event.type: 'loading' | 'activated' | 'deactivated' | 'loaded' | 'loadError'
+  // event.viewId: string
+  // event.element?: HTMLElement
+  // event.params?: Record<string, string>
+  // event.error?: unknown
+});
+
+// View change events
+appui.viewChanged$.subscribe((event) => {
+  // event.viewId: string
+  // event.view: IViewDefinition
+  // event.previousView?: IViewDefinition
+  // event.params?: Record<string, string>
+});
+```
+
+---
