## Technical Highlights

### Architecture Decisions
1. **Client-side only**: All components use `'use client'` directive for Next.js compatibility
2. **Tailwind CSS v4**: Styling with Tailwind classes, compatible with dark mode
3. **Type-safe**: Full TypeScript support with exported types
4. **Composable**: Built on `@mdxui/primitives` for consistency
5. **Accessible**: Using Radix UI primitives where applicable
6. **Performant**: Lazy loading of syntax highlighters, debounced autosave

### Design Patterns
- **Controlled components**: All editors accept `initialValue` and `onChange`
- **Flexible height**: Support both string and number values
- **Extensible**: Custom toolbars, renderers, and templates
- **Progressive enhancement**: Features can be toggled on/off
- **Error boundaries**: Graceful error handling with user feedback

### Styling Approach
- Uses `cn()` utility from `@mdxui/primitives/lib/utils`
- Tailwind classes for all styling
- Dark mode support via `dark:` variants
- Prose styling for rich text content
- Consistent with existing widgets

## License Compliance

All components are derived from or inspired by MIT-licensed projects:
- **Tiptap**: MIT License (https://github.com/ueberdosis/tiptap)
- **Minimal Tiptap**: MIT License (https://github.com/Aslam97/minimal-tiptap)
- **Shiki**: MIT License (https://github.com/shikijs/shiki)
- **React Markdown**: MIT License (https://github.com/remarkjs/react-markdown)

## Next Steps

To use these components:

1. **Install dependencies**:
   ```bash
   cd /Users/nathanclevenger/projects/db.sb/ui
   pnpm install
   ```

2. **Run Storybook**:
   ```bash
   pnpm storybook
   ```

3. **Import in your app**:
   ```tsx
   import { MarkdownEditor, CodeEditor, WYSIWYGEditor } from '@mdxui/widgets/editor/components'
   // Or individually:
   import { MarkdownEditor } from '@mdxui/widgets/editor/markdown'
   ```

4. **Type checking**:
   ```bash
   pnpm --filter @mdxui/widgets typecheck
   ```

## Testing Recommendations

1. **Unit tests**: Test utility functions in `utils.ts`
2. **Component tests**: Test each editor with various props
3. **Integration tests**: Test with autosave and sync hooks
4. **Visual regression**: Use Storybook for visual testing
5. **Accessibility**: Test keyboard navigation and screen readers

## Future Enhancements

Potential improvements:
1. Add more Tiptap extensions (images, mentions, emoji)
2. Implement collaborative cursor tracking
3. Add version history/undo stack visualization
4. Create template marketplace for EmailBuilder
5. Add export/import functionality for all formats
6. Implement find/replace functionality
7. Add spellcheck and grammar checking
8. Create mobile-optimized versions
9. Add AI-powered writing assistance hooks
10. Implement conflict resolution for sync
