- **Video Player**: ArtPlayer with HLS.js support
- **Deployment**: Docker multi-stage builds

### **Database Schema** ✅
```sql
-- Core Tables
libraries (id, path) -- Media library paths
media (id, library_id, path, type, title, size, thumbnail, rating, bookmarks) -- Media files
clusters (id, name, color, icon) -- Library organization  
bookmarks (id, media_id) -- User bookmarks
stars (id, media_id, rating) -- 1-5 star ratings
media_access (id, media_id, access_type) -- Recommendation tracking
```

### **API Endpoints** ✅
- **Libraries**: 4 endpoints (CRUD + scanning)
- **Media**: 6 endpoints (streaming, thumbnails, bookmarks, ratings)
- **Clusters**: 9 endpoints (full cluster management)
- **Recommendations**: 2 endpoints (Surprise Me system)
- **System**: 4 endpoints (health, status, processes)

## 🔄 **Development Workflow**

### **Rules** ✅
1. **Build Verification**: `pnpm build` after all changes
2. **Debug Logs**: Preserve until explicitly told to remove
3. **Documentation**: New guides in `docs/` folder (markdown)

### **Scripts**
```bash
pnpm dev          # Development server
pnpm build        # Production build with verification
pnpm buildprod    # Production build (no turbopack)
pnpm start        # Production server
```
