- **Default color**: Indigo (#6366f1)
- **Default icon**: folder
- **Cluster names**: Limited to 100 characters
- **Pagination**: Defaults to 50 items per page
- **UI Integration**: Combined Task 2.1 and 2.2 for better UX
### Technical Highlights:
- Zero-downtime migration (IF NOT EXISTS)
- Foreign key cascades for data integrity
- Optimized indexes for cluster queries
- Comprehensive error handling
- Input validation at both API and UI levels
- Real-time statistics with efficient queries
- Loading states for better UX
- Color-coded visual feedback
### UI/UX Features:
- Inline editing mode for clusters
- Visual color picker
- Icon selector with preview
- Multi-select library assignment
- Real-time statistics display
- Cluster badges on library cards
- Responsive design
- Loading skeletons
- Error messages with context
### Known Issues:
- None currently
### Performance Considerations:
- LibraryClusterBadges fetches all clusters then filters - could be optimized with dedicated API endpoint
- Consider caching cluster assignments in future iteration
