- admin Photos tab: add shared-album links (check, sync now, status/stale warnings),
  slideshow options, browser-resized uploads
- 6-hourly album sync scraping the share page (Library API no longer exposes
  user albums), caches 1920px + 64px copies in /data/photos
- /api/health/photos -> 503 when an album has not synced for 48h
- history/restore covers photo settings; min admin password length 6

+- `/photo`: full-screen photo frame with crossfade, a blurred backdrop or fill mode, shuffle, and the date taken.
+  - It picks up new settings and photos within about 30 seconds and reloads itself every 12 hours.
+- Admin **Photos** tab:
+  - Google Photos shared albums: paste the share link, use **Check**, and **Sync now**. The tab shows sync status, stale warnings and errors.
+  - Slideshow options.
+  - Photo uploads. Each upload is resized in the browser to 1920px plus a 64px backdrop thumbnail.
+- Albums sync every 6 hours (and 15 seconds after start).
+  - Each sync caches up to 500 photos per album at 1920px under `/data/photos`, skips videos, and removes photos deleted from the album.
+- `/api/health/photos` returns 503 when an enabled album has not synced for 48 hours.
+- History and Restore now cover photo settings too. A restore re-syncs any album it brings back.
