## Known Limitations & Notes

1. **Image Storage**: Files stored in `storage/app/public/` - ensure symlink created: `php artisan storage:link`
2. **Image Optimization**: Requires `intervention/image` package (should be already installed)
3. **File Size Counter**: `image_count` on galleries table is for performance - kept in sync via model events
4. **Soft Deletes**: Deleted records stay in database (paranoid pattern) - can be permanently purged via custom commands
5. **Image Dimensions**: Extracted from image headers during upload - helps with aspect ratio calculations

## Deployment Checklist

- [ ] Run migrations: `php artisan migrate`
- [ ] Run seeders: `php artisan db:seed --class=MediaPermissionSeeder` (or full `php artisan db:seed`)
- [ ] Create storage symlink: `php artisan storage:link`
- [ ] Clear config cache: `php artisan config:cache`
- [ ] Clear route cache: `php artisan route:cache`
- [ ] Test on staging environment before production
