Detailed implementation plan for automatic image optimization:
- Lossless WebP storage in SQLite (26-41% smaller than PNG)
- AVIF/WebP/JPEG responsive variants generated to disk cache
- Oban for durable async processing with SQLite
- 10-phase incremental implementation with checkpoints
- Comprehensive test coverage strategy
