- Create docs/FRONTEND_OPTIONS.md with comprehensive analysis
- Explore 4 options for separated frontend:
1. SPA with REST API (React/Vue/Svelte)
2. Hybrid approach (mobile SPA + desktop server templates)
3. HTMX for lightweight dynamic UI
4. Native mobile app (React Native/Flutter/Capacitor)
- Include comparison matrix with pros/cons
- Provide implementation examples for each option
- Add responsive design guidelines
- Include API endpoints specification
- Recommend phased implementation roadmap
- No code changes - documentation only
This addresses mobile responsiveness while keeping backend intact.
