A TypeScript web app for LG webOS TVs (webOS 5 / Chromium 68 and newer), driven by the remote: Movies and Series search with the Trakt lists, Library with status, title and file-property filters and download marks, seasons and episodes, release search and grab, Downloads, Calendar, Settings and Log. It talks to Radarr, Sonarr, SABnzbd and Trakt directly (they answer cross-origin requests); the arr-tui config is baked in at build time and can be changed on the TV. dev/screenshots/server.py answers cross-origin requests and accepts writes for it; webos/dev/drive.mjs drives the app in Chromium for screenshots.
