- Auto-save rendered Vue components to DB on render_vue_component
- Soft delete (archive) instead of hard delete for components
- Tags support for component categorization
- Gallery limited to 10 most recent items per section
- Upsert with ON CONFLICT for component saves
- PUT endpoint for partial component updates
- Collapsible toolbar with animated toggle button
- Window Controls Overlay support for PWA titlebar
- Compact header mode (32px) with hidden dot toggle
- Dynamic theme-color meta sync for Windows titlebar
