+
+## WYSIWYG Editor Architecture
+
+### Recent Refactoring (2025-06-24)
+
+The WYSIWYG editor has been refactored to improve maintainability and separation of concerns:
+
+#### New Handler Classes
+
+1. **WysiwygBlockOperations** (`wysiwyg.blockoperations.ts`)
+   - Manages all block-related operations
+   - Methods: createBlock, insertBlockAfter, removeBlock, findBlock, focusBlock, etc.
+   - Centralized block manipulation logic
+
+2. **WysiwygInputHandler** (`wysiwyg.inputhandler.ts`)
+   - Handles all input events for blocks
+   - Manages block content updates based on type
+   - Detects block type transformations
+   - Handles slash commands
+   - Manages auto-save with debouncing
+
+3. **WysiwygKeyboardHandler** (`wysiwyg.keyboardhandler.ts`)
+   - Handles all keyboard events
+   - Manages formatting shortcuts (Cmd/Ctrl + B/I/U/K)
+   - Handles special keys: Tab, Enter, Backspace
+   - Manages slash menu navigation
+
+4. **WysiwygDragDropHandler** (`wysiwyg.dragdrophandler.ts`)
+   - Manages drag and drop operations
+   - Tracks drag state
+   - Handles visual feedback during drag
+   - Manages block reordering
+
+5. **WysiwygModalManager** (`wysiwyg.modalmanager.ts`)
+   - Static methods for showing modals
+   - Language selection for code blocks
+   - Block settings modal
+   - Reusable modal patterns
+
+#### Main Component Updates
+
+The main `DeesInputWysiwyg` component now:
+- Instantiates handler classes in `connectedCallback`
+- Delegates complex operations to appropriate handlers
+- Maintains cleaner, more focused code
+- Better separation of concerns
+
+#### Benefits
+- Reduced main component size from 1100+ lines
+- Each handler class is focused on a single responsibility
+- Easier to test individual components
+- Better code organization
+- Improved maintainability
+
+#### Fixed Issues
+- Enter key no longer duplicates content in new blocks
+- Removed problematic `setBlockContents()` method
+- Content is now managed directly through DOM properties
+- Better timing for block creation and focus
+- Slash menu no longer disappears immediately on first "/" press
+- Focus is properly maintained when slash menu opens
+- Removed duplicate event handling methods from main component
+- Simplified focus management throughout the editor
+
+#### Additional Refactoring (2025-06-24 - Part 2)
+- **Removed duplicate code**: handleBlockInput and handleBlockKeyDown methods removed from main component
+- **Simplified focus management**: Removed complex lifecycle methods and timers
+- **Fixed slash menu behavior**: Changed to click events and proper event prevention
+- **dees-wysiwyg-block component**: Now uses static HTML rendering for better content control
+- **Improved formatting preservation**: HTML formatting (bold, italic, etc.) properly preserved in all block types
+
+#### Notes
+- All input handling now goes through WysiwygInputHandler
+- All keyboard handling goes through WysiwygKeyboardHandler
+- The slash menu uses click events instead of mousedown for better UX
+- Focus is maintained using requestAnimationFrame for better timing
+- The refactoring maintains all existing functionality with improved reliability
+
+### Global Menu Architecture (2025-06-24 - Part 3)
+
+The slash menu and formatting menu have been refactored to render globally instead of inside the wysiwyg component. This fixes focus loss issues that were occurring when the menus were re-rendered with the component.
+
+#### Key Components:
+
+1. **DeesSlashMenu** (`dees-slash-menu.ts`)
+   - Singleton component that renders globally in the document body
+   - Accessed via `DeesSlashMenu.getInstance()`
+   - Manages its own visibility, position, and filtering
+   - Emits callbacks when items are selected
+
+2. **DeesFormattingMenu** (`dees-formatting-menu.ts`)
+   - Singleton component that renders globally in the document body
+   - Accessed via `DeesFormattingMenu.getInstance()`
+   - Shows when text is selected
+   - Applies formatting commands via callback
+
+3. **Integration in DeesInputWysiwyg**
+   - Stores singleton instances: `private slashMenu = DeesSlashMenu.getInstance()`
+   - Shows menus with absolute positioning
+   - Menus handle their own rendering and state management
+
+#### Benefits:
+- No focus loss when menus appear/disappear
+- Better performance (menus don't re-render with component)
+- Cleaner separation of concerns
+- Menus persist across component updates
+
+#### Usage:
+```typescript
+// Show slash menu
+this.slashMenu.show(
+  { x: cursorX, y: cursorY },
+  (type: string) => this.insertBlock(type)
+);
+
+// Show formatting menu
+this.formattingMenu.show(
+  { x: selectionX, y: selectionY },
+  (command: string) => this.applyFormat(command)
+);
+```
+
+#### Previous Issues Fixed:
+- Slash menu was disappearing immediately on first "/" press
+- Focus was lost when menus appeared
+- Text selection was not working properly
+- Cursor position was lost after menu interactions
+
+### Arrow Key Navigation (2025-06-24 - Part 4)
+
+Enhanced arrow key handling for seamless navigation between blocks:
+
+#### Features:
+1. **ArrowUp at block start**: Automatically navigates to the end of the previous block
+2. **ArrowDown at block end**: Automatically navigates to the beginning of the next block
+3. **Smart detection**: Checks actual cursor position within the block content
+4. **Slash menu integration**: When slash menu is open, arrow keys navigate menu items instead
+5. **No focus loss**: Navigation maintains focus throughout
+
+#### Implementation:
+- Added `handleArrowUp()` and `handleArrowDown()` methods to `WysiwygKeyboardHandler`
+- Smart cursor position detection for different block types (text, lists, etc.)
+- Helper method `getLastTextNode()` for finding the last text position in complex HTML
+- Prevents default behavior only when navigating between blocks
+- Skips divider blocks during navigation
+
+### Focus Management Improvements (2025-06-24 - Part 5)
+
+Enhanced focus management to prevent focus loss during various operations:
+
+#### Key Improvements:
+
+1. **Formatting Without execCommand**:
+   - Replaced deprecated `document.execCommand` with modern DOM manipulation
+   - Proper selection restoration after formatting
+   - Async formatting operations to maintain focus
+
+2. **Link Dialog**:
+   - Replaced `prompt()` with custom modal dialog
+   - Maintains focus context during async operations
+   - Auto-focuses input field in modal
+
+3. **Robust Focus Methods**:
+   - Double `requestAnimationFrame` for DOM update timing
+   - Fallback focus attempts with microtasks
+   - Contenteditable attribute verification
+
+4. **Cursor Positioning**:
+   - Enhanced `setCursorToStart/End` with edge case handling
+   - Zero-width space insertion for empty elements
+   - Recursive node traversal for complex HTML structures
+
+5. **Async Keyboard Shortcuts**:
+   - Formatting shortcuts use Promise resolution
+   - Prevents focus loss during rapid keyboard input
+
+#### Implementation Details:
+- `focusWithCursor()` method now handles empty blocks and complex HTML
+- `applyFormat()` is async and properly restores selection
+- Link creation no longer uses blocking `prompt()` dialog
+- All focus operations use proper timing with RAF and microtasks
+
+### Focus Loss Prevention for Menus (2025-06-24 - Part 6)
+
+Fixed focus loss issues when slash menu and formatting menu appear:
+
+#### Key Fixes:
+
+1. **Timeout Reduction**:
+   - Replaced 50ms setTimeout with requestAnimationFrame
+   - Immediate focus attempt before falling back to RAF
+   - Reduced delay when inserting blocks
+
+2. **Menu Focus Prevention**:
+   - Added `tabindex="-1"` to prevent menus from taking focus
+   - Added focus event prevention on menus
+   - Menus now use mousedown prevention consistently
+
+3. **Blur Event Handling**:
+   - Skip value updates when slash menu is visible
+   - Prevent auto-save during slash menu interaction
+   - Maintain focus after menu appears with RAF
+
+4. **Block Focus Optimization**:
+   - Try immediate focus if block element exists
+   - Fall back to RAF only when necessary
+   - Consistent focus handling across all block types
+
+#### Implementation:
+- `handleBlockBlur()` checks if slash menu is visible before updating
+- `scheduleAutoSave()` skips saving when slash menu is open
+- Slash menu show adds RAF to restore focus if lost
+- Reduced timing delays throughout the focus chain
+
+### Slash Command Cleanup (2025-06-24 - Part 7)
+
+Fixed the issue where "/" remained in the editor after selecting a block type:
+
+#### The Fix:
+
+1. **In `insertBlock()`**:
+   - Clear slash command before transforming block type
+   - Use regex `/^\/[^\s]*\s*/` to match slash + filter text
+   - Trim the result to ensure clean content
+   - Set content to empty for transformed blocks
+
+2. **Improved Content Handling**:
+   - Wait for `updateComplete` before focusing
+   - Ensure lists start with empty content
+   - Consistent cleanup in both `insertBlock` and `closeSlashMenu`
+
+3. **Edge Cases**:
+   - Handle filtered commands (e.g., "/hea" for heading)
+   - Clear content even with partial matches
+   - Proper content reset for all block types
+
+Now when selecting a block type from the slash menu, the "/" and any filter text is properly removed before the block transformation occurs.
+
+### Enhanced Enter Key and Block Settings (2025-06-24 - Part 8)
+
+Added two major improvements to the wysiwyg editor:
+
+#### 1. Smart Enter Key Behavior:
+
+When pressing Enter, content after the cursor is now moved to the next block:
+
+- **Content Splitting**: Uses Range API to extract content after cursor
+- **HTML Preservation**: Maintains formatting when splitting blocks
+- **Clean Split**: Current block keeps content before cursor, new block gets content after
+- **Empty Block**: If cursor is at end, creates empty new block
+
+Implementation in `WysiwygKeyboardHandler.handleEnter()`:
+```typescript
+// Clone the range to extract content after cursor
+const afterRange = range.cloneRange();
+afterRange.selectNodeContents(target);
+afterRange.setStart(range.endContainer, range.endOffset);
+
+// Extract content after cursor
+const afterContent = afterRange.extractContents();
+```
+
+#### 2. Block Type Changing via Settings Menu:
+
+The block settings menu (three dots) now includes block type selection:
+
+- **Type Selector Grid**: Shows all available block types with icons
+- **Smart Metadata Handling**: 
+  - Clears code language when changing from code block
+  - Clears list type when changing from list
+  - Prompts for language when changing to code block
+- **Visual Feedback**: Currently selected type is highlighted
+- **Instant Update**: Block transforms immediately on selection
+
+Features:
+- Works for all block types (not just code blocks)
+- Preserves content during type transformation
+- Handles special cases like code block language selection
+- Modal closes automatically after selection
+
+### Complete WYSIWYG Refactoring (2025-06-24 - Part 9)
+
+Major architectural improvements to fix Enter key behavior and left arrow focus loss:
+
+#### 1. Async Operation Architecture:
+- All focus operations are now async with proper Promise handling
+- `insertBlockAfter()` waits for component updates before focusing
+- `focusBlock()` ensures DOM is ready with `updateComplete`
+- Eliminated arbitrary timeouts in favor of proper async/await
+
+#### 2. Enter Key Split Content Fix:
+- Added `getSplitContent()` method to block component
+- Properly extracts content before/after cursor using Range API
+- Updates current block and creates new block atomically
+- Content after cursor correctly moves to new block
+
+```typescript
+// In block component
+public getSplitContent(): { before: string; after: string } | null {
+  const beforeRange = range.cloneRange();
+  beforeRange.selectNodeContents(this.blockElement);
+  beforeRange.setEnd(range.startContainer, range.startOffset);
+  // ... extract and return split content
+}
+```
+
+#### 3. Arrow Key Navigation:
+- Added ArrowLeft/ArrowRight handlers for block boundaries
+- Prevents focus loss when navigating between blocks
+- Only intercepts at block boundaries, normal navigation otherwise
+- All arrow key operations are async for proper timing
+
+#### 4. Interface Architecture:
+Created `wysiwyg.interfaces.ts` with proper typing:
+- `IWysiwygComponent` - Main component contract
+- `IBlockOperations` - Block operation methods
+- `IWysiwygBlockComponent` - Block component interface
+- `IBlockEventHandlers` - Event handler signatures
+
+#### 5. Focus Management Improvements:
+- Eliminated double RAF in favor of single async flow
+- Focus operations wait for DOM updates via `updateComplete`
+- Proper cursor positioning after all operations
+- No more focus loss during navigation
+
+#### Key Changes:
+1. Keyboard handler methods are now async
+2. Block operations return Promises
+3. Enter key properly splits content at cursor
+4. Arrow keys handle block navigation without focus loss
+5. All timing is handled via proper async/await patterns
+
+The refactoring eliminates race conditions and timing issues that were causing focus loss and content duplication problems.
+
+### Programmatic Rendering Solution (2025-06-24 - Part 10)
+
+Fixed persistent focus loss issue by implementing fully programmatic rendering:
+
+#### The Problem:
+- User would click in a block, type text, then press arrow keys and lose focus
+- Root cause: Lit was re-rendering components when block content was mutated
+- Even with shouldUpdate() preventing re-renders, parent re-evaluation caused focus loss
+
+#### The Solution:
+
+1. **Static Parent Rendering**:
+   - Parent component renders only once with empty editor content div
+   - All blocks are created and managed programmatically via DOM manipulation
+   - No Lit re-renders triggered by state changes
+
+2. **Manual Block Management**:
+   - `renderBlocksProgrammatically()` creates all block elements manually
+   - `createBlockElement()` builds block wrapper with all event handlers
+   - `updateBlockElement()` replaces individual blocks when needed
+   - No reactive properties trigger parent re-renders
+
+3. **Content Update Strategy**:
+   - During typing, content is NOT immediately synced to data model
+   - Auto-save delayed to 2 seconds to avoid interference
+   - Content synced from DOM only on blur or before save
+   - `syncAllBlockContent()` reads from DOM when needed
+
+4. **Focus Preservation**:
+   - Block components prevent re-renders with `shouldUpdate()`
+   - Parent never re-renders after initial load
+   - Focus remains stable during all editing operations
+   - Arrow key navigation works without focus loss
+
+5. **Implementation Details**:
+   ```typescript
+   // Parent render method - static after first render
+   render(): TemplateResult {
+     return html`
+       <div class="editor-content" id="editor-content">
+         <!-- Blocks rendered programmatically -->
+       </div>
+     `;
+   }
+   
+   // All block operations use DOM manipulation
+   private renderBlocksProgrammatically() {
+     this.editorContentRef.innerHTML = '';
+     this.blocks.forEach(block => {
+       const blockWrapper = this.createBlockElement(block);
+       this.editorContentRef.appendChild(blockWrapper);
+     });
+   }
+   ```
+
+This approach completely eliminates focus loss by taking full control of the DOM and preventing any framework-induced re-renders during editing.
+
+### Code Refactoring and Cleanup (2025-06-24 - Part 11)
+
+Completed comprehensive refactoring to ensure clean, maintainable code with separated concerns:
+
+#### Refactoring Changes:
+
+1. **Drag and Drop Handler Cleanup**:
+   - Removed all `requestUpdate()` calls from drag handler
+   - Handler now only updates internal state
+   - Parent component handles DOM updates programmatically
+   - Simplified drag state management
+
+2. **Unused Code Removal**:
+   - Removed duplicate `showBlockSettingsModal` method (using WysiwygModalManager)
+   - Removed duplicate `showLanguageSelectionModal` method
+   - Removed unused `renderBlock` method
+   - Cleaned up unused imports (WysiwygBlocks, ISlashMenuItem)
+
+3. **Import Cleanup**:
+   - Removed unused type imports
+   - Organized imports logically
+   - Kept only necessary dependencies
+
+4. **Separated Concerns**:
+   - Modal management in WysiwygModalManager
+   - Block operations in WysiwygBlockOperations
+   - Input handling in WysiwygInputHandler
+   - Keyboard handling in WysiwygKeyboardHandler
+   - Drag/drop in WysiwygDragDropHandler
+   - Each class has a single responsibility
+
+5. **Programmatic DOM Management**:
+   - All DOM updates happen through explicit methods
+   - No reactive re-renders during user interaction
+   - Manual class management for drag states
+   - Direct DOM manipulation for performance
+
+6. **Test Files Created**:
+   - `test-focus-fix.html` - Verifies focus management
+   - `test-drag-drop.html` - Tests drag and drop functionality
+   - `test-comprehensive.html` - Tests all features together
+
+The refactoring follows the principles in instructions.md:
+- Uses static templates with manual DOM operations
+- Maintains separated concerns in different classes
+- Results in clean, concise, and manageable code
+
+## Z-Index Management System (2025-12-24)
+
+A comprehensive z-index management system has been implemented to fix overlay stacking conflicts:
+
+### The Problem:
+- Modals were hiding dropdown overlays
+- Context menus appeared behind modals
+- Inconsistent z-index values across components
+- No clear hierarchy for overlay stacking
+
+### The Solution:
+
+#### 1. Central Z-Index Constants (`00zindex.ts`):
+Created a centralized file defining all z-index layers:
+
+```typescript
+export const zIndexLayers = {
+  // Base layer: Regular content
+  base: {
+    content: 'auto',
+    inputElements: 1,
+  },
+  // Fixed UI elements
+  fixed: {
+    appBar: 10,
+    sideMenu: 10,
+    mobileNav: 250,
+  },
+  // Overlay backdrops
+  backdrop: {
+    dropdown: 1999,
+    modal: 2999,
+    contextMenu: 3999,
+  },
+  // Interactive overlays
+  overlay: {
+    dropdown: 2000,     // Dropdowns and select menus
+    modal: 3000,        // Modal dialogs
+    contextMenu: 4000,  // Context menus and tooltips
+    toast: 5000,        // Toast notifications
+  },
+  // Special cases
+  modalDropdown: 3500,    // Dropdowns inside modals
+  wysiwygMenus: 4500,     // Editor formatting menus
+}
+```
+
+#### 2. Updated Components:
+- **dees-modal**: Changed from 2000 to 3000
+- **dees-windowlayer**: Changed from 200-201 to 1999-2000 (used by dropdowns)
+- **dees-contextmenu**: Changed from 10000 to 4000
+- **dees-toast**: Changed from 10000 to 5000
+- **wysiwyg menus**: Changed from 10000 to 4500
+- **dees-appui-profiledropdown**: Uses new dropdown z-index (2000)
+
+#### 3. Stacking Order (bottom to top):
+1. Regular page content (auto)
+2. Fixed navigation elements (10-250)
+3. Dropdown backdrop (1999)
+4. Dropdown content (2000)
+5. Modal backdrop (2999)
+6. Modal content (3000)
+7. Context menu (4000)
+8. WYSIWYG menus (4500)
+9. Toast notifications (5000)
+
+#### 4. Key Benefits:
+- Dropdowns now appear above modals
+- Context menus appear above dropdowns and modals
+- Toast notifications always appear on top
+- Consistent and predictable stacking behavior
+- Easy to adjust hierarchy by modifying central constants
+
+#### 5. Testing:
+Created `test-zindex.demo.ts` to verify stacking behavior with:
+- Modal containing dropdown
+- Context menu on modal
+- Toast notifications
+- Complex overlay combinations
+
+### Usage:
+Import and use the z-index constants in any component:
+```typescript
+import { zIndexLayers } from './00zindex.js';
+
+// In styles
+z-index: ${zIndexLayers.overlay.modal};
+```
+

+# WYSIWYG Editor Refactoring Progress Summary
+
+## Latest Updates
+
+### Selection Highlighting Fix ✅
+- **Issue**: "Paragraphs are not highlighted consistently, headings are always highlighted"
+- **Root Cause**: The `shouldUpdate` method in `dees-wysiwyg-block.ts` was using a generic `.block` selector that would match the first element with that class, not necessarily the correct block element
+- **Solution**: Changed the selector to be more specific: `.block.${blockType}` which ensures the correct element is found for each block type
+- **Result**: All block types now highlight consistently when selected
+
+### Enter Key Block Creation Fix ✅
+- **Issue**: "When pressing enter and jumping to new block then typing something: The cursor is not at the beginning of the new block and there is content"
+- **Root Cause**: Block handlers were rendering content with template syntax `${block.content || ''}` in their render methods, which violates the static HTML principle
+- **Solution**: 
+  - Removed all `${block.content}` from render methods in paragraph, heading, quote, and code block handlers
+  - Content is now set programmatically in the setup() method only when needed
+  - Fixed `setCursorToStart` and `setCursorToEnd` to always find elements fresh instead of relying on cached `blockElement`
+- **Result**: New empty blocks remain truly empty, cursor positioning works correctly
+
+### Backspace Key Deletion Fix ✅
+- **Issue**: "After typing in a new block, pressing backspace deletes the whole block instead of just the last character"
+- **Root Cause**: 
+  1. `getCursorPositionInElement` was using `element.contains()` which doesn't work across Shadow DOM boundaries
+  2. The backspace handler was checking `block.content === ''` which only contains the stored content, not the actual DOM content
+- **Solution**:
+  1. Fixed `getCursorPositionInElement` to use `containsAcrossShadowDOM` for proper Shadow DOM support
+  2. Updated backspace handler to get actual content from DOM using `blockComponent.getContent()` instead of relying on stored `block.content`
+  3. Added debug logging to track cursor position and content state
+- **Result**: Backspace now correctly deletes individual characters instead of the whole block
+
+### Arrow Left Navigation Fix ✅
+- **Issue**: "When jumping to the previous block from the beginning of a block with arrow left, the cursor should be at the end of the previous block, not at the start"
+- **Root Cause**: Browser's default focus behavior places cursor at the beginning of contenteditable elements, overriding our cursor positioning
+- **Solution**: For 'end' position, set up the selection range BEFORE focusing the element:
+  1. Create a range pointing to the end of content
+  2. Apply the selection
+  3. Then focus the element (which preserves the existing selection)
+  4. Only use setCursorToEnd for empty blocks
+- **Result**: Arrow left navigation now correctly places cursor at the end of the previous block
+
+## Completed Phases
+
+### Phase 1: Infrastructure ✅
+- Created modular block handler architecture
+- Implemented `IBlockHandler` interface and `BaseBlockHandler` class
+- Created `BlockRegistry` for dynamic block type registration
+- Set up proper file structure under `blocks/` directory
+
+### Phase 2: Proof of Concept ✅
+- Successfully migrated divider block as the simplest example
+- Validated the architecture works correctly
+- Established patterns for block migration
+
+### Phase 3: Text Blocks ✅
+- **Paragraph Block**: Full editing support with text splitting, selection handling, and cursor tracking
+- **Heading Blocks**: All three heading levels (h1, h2, h3) with unified handler
+- **Quote Block**: Italic styling with border, full editing capabilities
+- **Code Block**: Monospace font, tab handling, plain text paste support
+- **List Block**: Bullet/numbered lists with proper list item management
+
+## Key Achievements
+
+### 1. Preserved Critical Knowledge
+- **Static Rendering**: Blocks use `innerHTML` in `firstUpdated` to prevent focus loss during typing
+- **Shadow DOM Selection**: Implemented `containsAcrossShadowDOM` utility for proper selection detection
+- **Cursor Position Tracking**: All editable blocks track cursor position across multiple events
+- **Content Splitting**: HTML-aware splitting using Range API preserves formatting
+- **Focus Management**: Microtask-based focus restoration ensures reliable cursor placement
+
+### 2. Enhanced Architecture
+- Each block type is now self-contained in its own file
+- Block handlers are dynamically registered and loaded
+- Common functionality is shared through base classes
+- Styles are co-located with their block handlers
+
+### 3. Maintained Functionality
+- All keyboard navigation works (arrows, backspace, delete, enter)
+- Text selection across Shadow DOM boundaries functions correctly
+- Block merging and splitting behave as before
+- IME (Input Method Editor) support is preserved
+- Formatting shortcuts (Cmd/Ctrl+B/I/U/K) continue to work

+
+### Phase 5: Content Blocks
+- Markdown block with preview toggle
+- HTML block with raw HTML editing
+
+### Phase 6: Cleanup
+- Remove old code from main component
+- Optimize bundle size
+- Update documentation
+
+## Technical Improvements
+
+1. **Modularity**: Each block type is now completely self-contained
+2. **Extensibility**: New blocks can be added by creating a handler and registering it
+3. **Maintainability**: Files are smaller and focused on single responsibilities
+4. **Type Safety**: Strong TypeScript interfaces ensure consistent implementation
+5. **Performance**: No degradation in performance; potential for lazy loading in future
+
+## Migration Pattern
+
+For future block migrations, follow this pattern:
+
+1. Create block handler extending `BaseBlockHandler`
+2. Implement required methods: `render()`, `setup()`, `getStyles()`
+3. Add helper methods for cursor/content management
+4. Handle Shadow DOM selection properly using utilities
+5. Register handler in `wysiwyg.blockregistration.ts`
+6. Test all interactions (typing, selection, navigation)
+
+The refactoring has been successful in making the codebase more maintainable while preserving all the hard-won functionality and edge case handling from the original implementation.

+# WYSIWYG Editor Refactoring
+
+## Summary of Changes
+
+This refactoring cleaned up the wysiwyg editor implementation to fix focus, cursor position, and selection issues.
+
+### Phase 1: Code Organization
+
+#### 1. Removed Duplicate Code
+- Removed duplicate `handleBlockInput` method from main component (was already in inputHandler)
+- Removed duplicate `handleBlockKeyDown` method from main component (was already in keyboardHandler)
+- Consolidated all input handling in the respective handler classes
+
+#### 2. Simplified Focus Management
+- Removed complex `updated` lifecycle method that was trying to maintain focus
+- Simplified `handleBlockBlur` to not immediately close menus
+- Added `requestAnimationFrame` to focus operations for better timing
+- Removed `slashMenuOpenTime` tracking which was no longer needed
+
+#### 3. Fixed Slash Menu Behavior
+- Changed from `@mousedown` to `@click` events for better UX
+- Added proper event prevention to avoid focus loss
+- Menu now closes when clicking outside
+- Simplified the insertBlock method to close menu first
+
+### Phase 2: Cursor & Selection Fixes
+
+#### 4. Enhanced Cursor Position Management
+- Added `focusWithCursor()` method to block component for precise cursor positioning
+- Improved `handleSlashCommand` to preserve cursor position when menu opens
+- Added `getCaretCoordinates()` for accurate menu positioning based on cursor location
+- Updated `focusBlock()` to support numeric cursor positions
+
+#### 5. Fixed Selection Across Shadow DOM
+- Added custom `block-text-selected` event to communicate selections across shadow boundaries
+- Implemented `handleMouseUp()` in block component to detect selections
+- Updated main component to listen for selection events from blocks
+- Selection now works properly even with nested shadow DOMs
+
+#### 6. Improved Slash Menu Close Behavior
+- Added optional `clearSlash` parameter to `closeSlashMenu()`
+- Escape key now properly clears the slash command
+- Clicking outside clears the slash if menu is open
+- Selecting an item preserves content and just transforms the block
+
+### Technical Improvements
+
+#### Block Component (`dees-wysiwyg-block`)
+- Better focus management with immediate focus (removed unnecessary requestAnimationFrame)
+- Added cursor position control methods
+- Custom event dispatching for cross-shadow-DOM communication
+- Improved content handling for different block types
+
+#### Input Handler
+- Preserves cursor position when showing slash menu
+- Better caret coordinate calculation for menu positioning
+- Ensures focus stays in the block when menu appears
+
+#### Block Operations
+- Enhanced `focusBlock()` to support start/end/numeric positions
+- Better timing with requestAnimationFrame for focus operations
+
+### Key Benefits
+- Slash menu no longer causes focus or cursor position loss
+- Text selection works properly across shadow DOM boundaries
+- Cursor position is preserved when interacting with menus
+- Cleaner, more maintainable code structure
+- Better separation of concerns
+
+## Testing
+
+Use the test files in `.nogit/debug/`:
+- `test-slash-menu.html` - Tests slash menu focus behavior
+- `test-wysiwyg-formatting.html` - Tests text formatting
+
+## Known Issues Fixed
+- Slash menu disappearing immediately on first "/"

+# WYSIWYG Block Cleanup Status
+
+## Overview
+This document tracks the cleanup of `dees-wysiwyg-block.ts` after migrating all block types to the new block handler architecture.
+
+## Completed ✅
+All cleanup tasks have been successfully completed on 2025-06-26.
+
+## Cleanup Tasks
+
+### 1. ✅ Remove Block-Specific Styles (lines 101-219)
+- [x] Remove `.block.heading-1/2/3` styles → Now in `heading.block.ts`
+- [x] Remove `.block.quote` styles → Now in `quote.block.ts`
+- [x] Remove `.block.list` styles → Now in `list.block.ts`
+- [x] Remove `.block.paragraph` styles → Now in `paragraph.block.ts`
+
+### 2. ✅ Remove Code Block Specific Logic
+- [x] Remove code block rendering in `renderBlockContent()` (lines 508-521)
+- [x] Remove all `type === 'code'` conditional branches
+- [x] Simplify element selection to not special-case code blocks
+
+### 3. ✅ Remove List Block Specific Logic
+- [x] Remove `focusListItem()` method (lines 814-821)
+- [x] Remove list-specific handling in `getContent()` (lines 732-734)
+- [x] Remove list-specific handling in `setContent()` (lines 764-765)
+- [x] Remove list content rendering in `firstUpdated()` (line 479)
+
+### 4. ✅ Remove getPlaceholder() Method
+- [x] Remove entire method (lines 538-553)
+- [x] Update renderBlockContent() to not use placeholders
+
+### 5. ✅ Clean Up Excessive Empty Lines
+- [x] Remove consecutive blank lines throughout the file
+
+### 6. ✅ Centralize nonEditableTypes
+- [x] Create a single source of truth for non-editable block types
+- [x] Remove duplicate arrays
+
+### 7. ✅ Simplify Handler Delegation
+- [x] Keep handler delegation pattern but ensure consistency
+
+### 8. ✅ Remove Unused Properties (if confirmed unused)
+- [x] Keep `contentInitialized` - still used for tracking
+- [x] Keep `blockElement` - used for caching
+- [x] Keep cursor tracking properties - used for selection
+
+## Implementation Notes
+
+### Block Types Now Fully Handled by Handlers:
+1. **Text blocks**: paragraph, heading-1/2/3, quote, code, list
+2. **Media blocks**: image, youtube, attachment  
+3. **Content blocks**: divider, markdown, html
+
+### Remaining Responsibilities of dees-wysiwyg-block.ts:
+1. Shadow DOM container management
+2. Handler delegation for all operations
+3. Generic block wrapper styles
+4. Selection/cursor tracking
+5. Event listener setup (until fully delegated to handlers)
+
+## Future Improvements
+- Consider moving all event handling to block handlers
+- Simplify the handler delegation pattern
+- Move generic block styles to a shared location
+- Consider removing the need for special-casing any block types

+# Critical WYSIWYG Knowledge - DO NOT LOSE
+
+This document captures all the hard-won knowledge from our WYSIWYG editor development. These patterns and solutions took significant effort to discover and MUST be preserved during refactoring.
+
+## 1. Static Rendering to Prevent Focus Loss
+
+### Problem
+When using Lit's reactive rendering, every state change would cause a re-render, which would:
+- Lose cursor position
+- Lose focus state
+- Interrupt typing
+- Break IME (Input Method Editor) support
+
+### Solution
+We render blocks **statically** and manage updates imperatively:
+
+```typescript
+// In dees-wysiwyg-block.ts
+render(): TemplateResult {
+  if (!this.block) return html``;
+  // Render empty container - content set in firstUpdated
+  return html`<div class="wysiwyg-block-container"></div>`;
+}
+
+firstUpdated(): void {
+  const container = this.shadowRoot?.querySelector('.wysiwyg-block-container');
+  if (container && this.block) {
+    container.innerHTML = this.renderBlockContent();
+  }
+}
+```
+
+### Critical Pattern
+- NEVER use reactive properties that would trigger re-renders during typing
+- Use `shouldUpdate()` to prevent unnecessary renders
+- Manage content updates imperatively through event handlers
+
+## 2. Shadow DOM Selection Handling
+
+### Problem
+The Web Selection API doesn't work across Shadow DOM boundaries by default. This broke:
+- Text selection
+- Cursor position tracking
+- Formatting detection
+- Content splitting for Enter key
+
+### Solution
+Use the `getComposedRanges` API with all relevant shadow roots:
+
+```typescript
+// From paragraph.block.ts
+const wysiwygBlock = element.closest('dees-wysiwyg-block');
+const parentComponent = wysiwygBlock?.closest('dees-input-wysiwyg');
+const parentShadowRoot = parentComponent?.shadowRoot;
+const blockShadowRoot = (wysiwygBlock as any)?.shadowRoot;
+
+const shadowRoots: ShadowRoot[] = [];
+if (parentShadowRoot) shadowRoots.push(parentShadowRoot);
+if (blockShadowRoot) shadowRoots.push(blockShadowRoot);
+
+const selectionInfo = WysiwygSelection.getSelectionInfo(...shadowRoots);
+```
+
+### Critical Pattern
+- ALWAYS collect all shadow roots in the hierarchy
+- Use `WysiwygSelection` utility methods that handle shadow DOM
+- Never use raw `window.getSelection()` without shadow root context
+
+## 3. Cursor Position Tracking
+
+### Problem
+Cursor position would be lost during various operations, making it impossible to:
+- Split content at the right position for Enter key
+- Restore cursor after operations
+- Track position for formatting
+
+### Solution
+Track cursor position through multiple events and maintain `lastKnownCursorPosition`:
+
+```typescript
+// Track on every relevant event
+private lastKnownCursorPosition: number = 0;
+
+// In event handlers:
+const pos = this.getCursorPosition(element);
+if (pos !== null) {
+  this.lastKnownCursorPosition = pos;
+}
+
+// Fallback when selection not available:
+if (!selectionInfo && this.lastKnownCursorPosition !== null) {
+  // Use last known position
+}
+```
+
+### Critical Events to Track
+- `input` - After text changes
+- `keydown` - Before key press
+- `keyup` - After key press
+- `mouseup` - After mouse selection
+- `click` - With setTimeout(0) for browser to set cursor
+
+## 4. Content Splitting for Enter Key
+
+### Problem
+Splitting content at cursor position while preserving HTML formatting was complex due to:
+- Need to preserve formatting tags
+- Shadow DOM complications
+- Cursor position accuracy
+
+### Solution
+Use Range API to split content while preserving HTML:
+
+```typescript
+getSplitContent(): { before: string; after: string } | null {
+  // Create ranges for before and after cursor
+  const beforeRange = document.createRange();
+  const afterRange = document.createRange();
+  
+  beforeRange.setStart(element, 0);
+  beforeRange.setEnd(selectionInfo.startContainer, selectionInfo.startOffset);
+  
+  afterRange.setStart(selectionInfo.startContainer, selectionInfo.startOffset);
+  afterRange.setEnd(element, element.childNodes.length);
+  
+  // Extract HTML content
+  const beforeFragment = beforeRange.cloneContents();
+  const afterFragment = afterRange.cloneContents();
+  
+  // Convert to HTML strings
+  const tempDiv = document.createElement('div');
+  tempDiv.appendChild(beforeFragment);
+  const beforeHtml = tempDiv.innerHTML;
+  
+  tempDiv.innerHTML = '';
+  tempDiv.appendChild(afterFragment);
+  const afterHtml = tempDiv.innerHTML;
+  
+  return { before: beforeHtml, after: afterHtml };
+}
+```
+
+## 5. Focus Management
+
+### Problem
+Focus would be lost or not properly set due to:
+- Timing issues with DOM updates
+- Shadow DOM complications
+- Browser inconsistencies
+
+### Solution
+Use defensive focus management with fallbacks:
+
+```typescript
+focus(element: HTMLElement): void {
+  const block = element.querySelector('.block');
+  if (!block) return;
+  
+  // Ensure focusable
+  if (!block.hasAttribute('contenteditable')) {
+    block.setAttribute('contenteditable', 'true');
+  }
+  
+  block.focus();
+  
+  // Fallback with microtask if focus failed
+  if (document.activeElement !== block && element.shadowRoot?.activeElement !== block) {
+    Promise.resolve().then(() => {
+      block.focus();
+    });
+  }
+}
+```
+
+## 6. Selection Event Handling for Formatting
+
+### Problem
+Need to show formatting menu when text is selected, but selection events don't bubble across Shadow DOM.
+
+### Solution
+Dispatch custom events with selection information:
+
+```typescript
+// Listen for selection changes
+document.addEventListener('selectionchange', () => {
+  const selectionInfo = WysiwygSelection.getSelectionInfo(...shadowRoots);
+  
+  if (selectedText !== this.lastSelectedText) {
+    const range = WysiwygSelection.createRangeFromInfo(selectionInfo);
+    const rect = range.getBoundingClientRect();
+    
+    // Dispatch custom event
+    this.dispatchSelectionEvent(element, {
+      text: selectedText,
+      blockId: block.id,
+      range: range,
+      rect: rect,
+      hasSelection: true
+    });
+  }
+});
+
+// Custom event bubbles through Shadow DOM
+const event = new CustomEvent('block-text-selected', {
+  detail,
+  bubbles: true,
+  composed: true
+});
+```
+
+## 7. IME (Input Method Editor) Support
+
+### Problem
+Composition events for non-Latin input methods would break without proper handling.
+
+### Solution
+Track composition state and handle events:
+
+```typescript
+// In dees-input-wysiwyg.ts
+public isComposing: boolean = false;
+
+// In block handlers
+element.addEventListener('compositionstart', () => {
+  handlers.onCompositionStart(); // Sets isComposing = true
+});
+
+element.addEventListener('compositionend', () => {
+  handlers.onCompositionEnd(); // Sets isComposing = false
+});
+
+// Don't process certain operations during composition
+if (this.isComposing) return;
+```
+
+## 8. Programmatic Rendering
+
+### Problem
+Lit's declarative rendering would cause focus loss and performance issues with many blocks.
+
+### Solution
+Render blocks programmatically:
+
+```typescript
+public renderBlocksProgrammatically() {
+  if (!this.editorContentRef) return;
+  
+  // Clear existing blocks
+  this.editorContentRef.innerHTML = '';
+  
+  // Create and append block elements
+  this.blocks.forEach(block => {
+    const blockWrapper = this.createBlockElement(block);
+    this.editorContentRef.appendChild(blockWrapper);
+  });
+}
+```
+
+## 9. Block Handler Architecture Requirements
+
+When creating new block handlers, they MUST:
+
+1. **Implement all cursor/selection methods** even if not applicable
+2. **Use Shadow DOM-aware selection utilities**
+3. **Track cursor position through events**
+4. **Handle focus with fallbacks**
+5. **Preserve HTML content when getting/setting**
+6. **Dispatch selection events for formatting**
+7. **Support IME composition events**
+8. **Clean up event listeners on disconnect**
+
+## 10. Testing Considerations
+
+### webhelpers.fixture() Issue
+The test helper `webhelpers.fixture()` triggers property changes during initialization that can cause null reference errors. Always:
+
+1. Check for null/undefined before accessing nested properties
+2. Set required properties in specific order when testing
+3. Consider manual element creation for complex test scenarios
+
+## Summary
+
+These patterns represent hours of debugging and problem-solving. When refactoring:
+
+1. **NEVER** remove static rendering approach
+2. **ALWAYS** use Shadow DOM-aware selection utilities
+3. **MAINTAIN** cursor position tracking through all events
+4. **PRESERVE** the complex content splitting logic
+5. **KEEP** all focus management fallbacks
+6. **ENSURE** selection events bubble through Shadow DOM
+7. **SUPPORT** IME composition events
+8. **TEST** thoroughly with actual typing, not just unit tests
+
+Any changes that break these patterns will result in a degraded user experience that took significant effort to achieve.

+# Phase 2 Implementation Summary - Divider Block Migration
+
+## Overview
+Successfully migrated the divider block to the new block handler architecture as a proof of concept.
+
+## Changes Made
+
+### 1. Created Block Handler
+- **File**: `blocks/content/divider.block.ts`
+- Implemented `DividerBlockHandler` class extending `BaseBlockHandler`
+- Extracted divider rendering logic from `dees-wysiwyg-block.ts`
+- Extracted divider setup logic (event handlers)
+- Extracted divider-specific styles
+
+### 2. Registration System
+- **File**: `wysiwyg.blockregistration.ts`
+- Created registration module that registers all block handlers
+- Currently registers only the divider handler
+- Includes placeholders for future block types
+
+### 3. Updated Block Component
+- **File**: `dees-wysiwyg-block.ts`
+- Added import for BlockRegistry and handler types
+- Modified `renderBlockContent()` to check registry first
+- Modified `firstUpdated()` to use registry for setup
+- Added `injectHandlerStyles()` method to inject handler styles dynamically
+- Removed hardcoded divider rendering logic
+- Removed hardcoded divider styles
+- Removed `setupDividerBlock()` method
+
+### 4. Updated Exports
+- **File**: `blocks/index.ts`
+- Exported `DividerBlockHandler` class
+
+## Key Features Preserved
+✅ Visual appearance with gradient and icon
+✅ Click to select behavior  
+✅ Keyboard navigation support (Tab, Arrow keys)
+✅ Deletion with backspace/delete
+✅ Focus/blur handling
+✅ Proper styling for selected state
+
+## Architecture Benefits
+1. **Modularity**: Each block type is now self-contained
+2. **Maintainability**: Block-specific logic is isolated
+3. **Extensibility**: Easy to add new block types
+4. **Type Safety**: Proper TypeScript interfaces
+5. **Code Reuse**: Common functionality in BaseBlockHandler
+
+## Next Steps
+To migrate other block types, follow this pattern:
+1. Create handler file in appropriate folder (text/, media/, content/)
+2. Extract render logic, setup logic, and styles
+3. Register in `wysiwyg.blockregistration.ts`
+4. Remove hardcoded logic from `dees-wysiwyg-block.ts`
+5. Export from `blocks/index.ts`
+
+## Testing
+- Project builds successfully without errors
+- Existing tests pass
+- Divider blocks render and function identically to before

+# Phase 4 Implementation Summary - Heading Blocks Migration
+
+## Overview
+Successfully migrated all heading blocks (h1, h2, h3) to the new block handler architecture using a unified HeadingBlockHandler class.
+
+## Changes Made
+
+### 1. Created Unified Heading Handler
+- **File**: `blocks/text/heading.block.ts`
+- Implemented `HeadingBlockHandler` class extending `BaseBlockHandler`
+- Single handler class that accepts heading level (1, 2, or 3) in constructor
+- Extracted all heading rendering logic from `dees-wysiwyg-block.ts`
+- Extracted heading setup logic with full text editing support:
+  - Input handling with cursor tracking
+  - Selection handling with Shadow DOM support
+  - Focus/blur management
+  - Composition events for IME support
+  - Split content functionality
+- Extracted all heading-specific styles for all three levels
+
+### 2. Registration Updates
+- **File**: `wysiwyg.blockregistration.ts`
+- Registered three heading handlers using the same class:
+  - `heading-1` → `new HeadingBlockHandler('heading-1')`
+  - `heading-2` → `new HeadingBlockHandler('heading-2')`
+  - `heading-3` → `new HeadingBlockHandler('heading-3')`
+- Updated imports to include HeadingBlockHandler
+
+### 3. Updated Exports
+- **File**: `blocks/index.ts`
+- Exported `HeadingBlockHandler` class
+- Removed TODO comment for heading handler
+
+### 4. Handler Implementation Details
+- **Dynamic Level Handling**: The handler determines the heading level from the block type
+- **Shared Styles**: All heading levels share the same style method but render different CSS
+- **Placeholder Support**: Each level has its own placeholder text
+- **Full Text Editing**: Inherits all paragraph-like functionality:
+  - Cursor position tracking
+  - Text selection with Shadow DOM awareness
+  - Content splitting for Enter key handling
+  - Focus management with cursor positioning
+
+## Key Features Preserved
+✅ All three heading levels render with correct styles
+✅ Font sizes: h1 (32px), h2 (24px), h3 (20px)
+✅ Proper font weights and line heights
+✅ Theme-aware colors using cssManager.bdTheme
+✅ Contenteditable functionality
+✅ Selection and cursor tracking
+✅ Keyboard navigation
+✅ Focus/blur handling
+✅ Placeholder text for empty headings
+
+## Architecture Benefits
+1. **Code Reuse**: Single handler class for all heading levels
+2. **Consistency**: All headings share the same behavior
+3. **Maintainability**: Changes to heading behavior only need to be made once
+4. **Type Safety**: Heading level is type-checked at construction
+5. **Scalability**: Easy to add more heading levels if needed
+
+## Testing Results
+- ✅ TypeScript compilation successful
+- ✅ All three heading handlers registered correctly
+- ✅ Render method produces correct HTML with proper classes
+- ✅ Placeholders set correctly for each level
+- ✅ All handlers are instances of HeadingBlockHandler
+
+## Next Steps
+Continue with Phase 5 to migrate remaining text blocks:
+- Quote block
+- Code block
+- List block
+
+Each will follow the same pattern but with their specific requirements.

+        <h4>Best Practices:</h4>
+        <ul>
+          <li>Always use the z-index registry from <code>00zindex.ts</code></li>
+          <li>Never use arbitrary z-index values like <code>z-index: 9999</code></li>
+          <li>Get z-index from registry when showing elements: <code>zIndexRegistry.getNextZIndex()</code></li>
+          <li>Register elements to track them: <code>zIndexRegistry.register(element, zIndex)</code></li>
+          <li>Unregister on cleanup: <code>zIndexRegistry.unregister(element)</code></li>
+          <li>Elements created later automatically appear on top</li>
+          <li>Test overlay interactions, especially dropdowns in modals</li>
+          <li>WYSIWYG menus (slash commands, formatting) now use dynamic z-index</li>
+        </ul>
+
+        <h4>Import Example:</h4>
+        <pre style="background: ${cssManager.bdTheme('#f5f5f5', '#2a2a2a')}; padding: 16px; border-radius: 6px; overflow-x: auto;">
+<code>import { zIndexRegistry } from './00zindex.js';
+
+// In your component:
+const myZIndex = zIndexRegistry.getNextZIndex();
+element.style.zIndex = myZIndex.toString();
+zIndexRegistry.register(element, myZIndex);
+
+// On cleanup:
+zIndexRegistry.unregister(element);</code></pre>
