- Admin: user management tab with favorites/reviews detail
- Admin: channel deletion fix for IDs with slashes
- Frontend: responsive mobile layout (map top, list bottom, 2-row header)
- Frontend: channel-colored map markers with legend
- Frontend: my reviews list, favorites toggle, visit counter overlay
- Frontend: force light mode for dark theme devices
- Backend: visit tracking (site_visits table), user reviews endpoint
- Backend: bulk transcript/extract streaming, geocode key fixes
- Nginx config for production deployment
