+- `/photo/gallery`: a remote-driven photo grid for the Shield photo app's launcher tile.
+  - Arrows move between tiles, OK opens a photo full screen with a zoom-in, and ◀ ▶ browse while it is open.
+  - Back (or OK) returns to the grid, and a **Slideshow** button at the top starts `/photo`.
+  - Photos are shown newest first.
+  - After 10 minutes without a key press, the slideshow starts on its own. The app keeps the screen on, so the TV screensaver never would.
+- Sync now also caches a 400px gallery tile (`<key>.m.jpg`) per photo. Existing albums backfill on their next sync.
+  - Admin uploads send a tile too. Older uploads without one use the full photo in the grid.
+- `/api/photos` entries gain a `tile` field.
+- Shield photo app `com.dayline.photos` 1.1 (versionCode 2):
+  - The launcher tile opens the gallery and takes D-pad input.
+  - Back steps back through the gallery's history (closing a full-screen photo) before exiting.
+  - The screensaver is unchanged (non-interactive slideshow).

 # 1.2.0 (2026-11-04)
 
 - `/photo`: full-screen photo frame with crossfade, a blurred backdrop or fill mode, shuffle, and the date taken.
