CogentialandClaude Opus 5.5 dca76585bc Discover new Steam Frame apps on GitHub 
Searches GitHub (steam-frame topic, "steam frame" in names/descriptions) and the
awesome-steam-frame list, checks each project's releases for a download the Frame can
install, and lists them with New badges, in the headset app (X / Discover row) and on the
web page. Cached, rechecked only when a repo changes, and limited per run so update
checks keep enough of GitHub's unauthenticated rate limit.

/* Frametanium for the headset: a controller-driven front end for the Frametanium service (manager.py), which
* does the downloading and installing. It talks to the service on 127.0.0.1 with plain HTTP and reads simple
* tab-separated replies.
*
* Screens: the app list; an app's menu (install/update, versions, previous version, pre-releases, remove); adding
* an app (type a GitHub repo on an on-screen keyboard, paste a link, or pick a suggestion); discover (new Steam Frame
* projects on GitHub with a release to install); and the found repo, where you pick its download and add it.
*
* Controls: D-pad/left stick to choose, A select, B back/close, Y add an app, X discover, Select update all, Start
* check for updates. Keyboard: arrows, Enter, Esc, and typing on the on-screen keyboard screen. */
