# 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
