binarygeek119/screenstage ? reverse-engineered prompt

Build me a digital poster display app for a TV or kiosk screen that shows movie, show, music, book, and audiobook posters from Plex, Jellyfin, Emby, Kodi, Sonarr, Radarr, and Readarr.

It should cycle through current playing items and random library titles, show nice artwork and background images, and include useful metadata like runtime, rating, studio, cast, and similar details. I also want a sleep timer, support for portrait and landscape screens, a way to hide the footer when the mouse goes to the bottom, and optional TV or movie theme music if available.

Please include a settings page where I can connect my media sources, adjust display options, manage cache and sync, and configure things like trivia, custom slides, and Awtrix support. Add a dedicated now showing view for upcoming movies with showtimes, plus an ads view that can rotate promo slides. If you need to check current docs or APIs, look them up online.
