 ## Completed UI Cleanup
 - Home page now acts as a lightweight landing page with direct links to Library and Gameday.
 - Removed the old game-list-heavy dashboard content that was not useful as a landing surface.
+- Game titles in the UI now include a day parenthetical such as `(sun 5/3)` wherever the shared formatter is used.
 
 ## Storage Status
 - Backend media persists in the `backend-media` named Docker volume.
