Summary

• Libre.fm: sign in with the authToken form of auth.getMobileSession (MD5 of the lower-cased user name and the password's MD5), which is the only form GNU FM accepts. Last.fm keeps the password form.
• Auto quality: the 1080p cap now applies only to low-RAM devices. Since fix(player): SponsorBlock filler and preview, live quality caps, subtitle diagnostics #1137 it applied to every app heap of 256 MB or less, which held live Auto, the VOD Auto ladder and Shorts at 1080p on most phones. The screen viewport still keeps Auto at the display's class.
• Decoder give-up: the player saves its place before it is emptied. Play, Retry and a quality change resume there, and Retry reloads the streams the player already has instead of extracting the video again. An app resume leaves the reload to the error screen's Retry.
• New setting in Appearance › Player: Progress Bar With Hidden Controls, with On video (default, unchanged), Below and Off, on the shared connected toggle group. Below hangs the strip under the video edge as a draw-only bar, so taps on the bottom of the picture reach the player.

Screenshots or recordings

Risk and compatibility

• Player path: the track selector's device cap and the decoder give-up path. Phones that are not low-RAM can now pick 1440p or 4K in Auto when the screen is large enough. Playback memory stays bounded by the buffer byte targets.

• New device-scoped preference portrait_idle_progress_bar, default On video. No Room change.

• The change does not introduce secrets, private data, or unexpected telemetry.

• New user-facing text uses Android string resources.

• Dependency and lockfile changes are intentional and limited to this PR.

• Room schema changes include the required version bump and migration, or this PR does not change the Room schema.

• Breaking changes and upgrade steps are clearly documented.
