📝 Notes

Design Decisions:

• Colors: 8 predefined colors (Indigo, Blue, Green, Red, Purple, Pink, Orange, Yellow)
• Icons: 10 icons (folder, film, tv, image, book, database, archive, star, heart, flag)
• Color format: Hex format (#RRGGBB) with validation
• 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
