Subshell 0.80-beta

Subshell 0.80: Material 3 throughout, a new video player and better accessibility

Highlights:

• Material 3 throughout: one top bar per screen, a navigation rail on tablets and foldables, list rows and segmented choices in Settings.
• Video: a new seek bar with live frames, playback options in post and full screen, speed, double-tap skip, hold for 2x and picture-in-picture (each optional).
• Wi-Fi only autoplay now really holds autoplay on mobile data; playing video keeps the screen on, and unplugging headphones pauses.
• A Video group in Settings: subtitles, audio language, timeline size, quality and where the playback options show.
• Better contrast, screen-reader labels and large-text layouts across the app.
• Defaults reviewed: the theme follows the system, unread markers are on, and a one-time tip points to Settings.
• Comments removed by a moderator are marked Removed in the thread.
• NSFW: searches follow Show NSFW posts, quarantined communities can be opted into, banned and private ones say why; optional random NSFW community.
• Errors appear in one tray instead of pop-ups; an image that can never load offers Open in browser.
• Images linked over http load over https; a link to an image host stays a link.
• Fixes: GIFs on your own profile autoplay again, lists without a top bar scroll by touch, Hidden tab for local accounts, link decoding on Android 8-12.
• Many internal checks replaced by behaviour tests, and every land now runs a lint gate.

Under the hood:

• Step 3 of the checker clean-up is done: the old source-pinning checkers were replaced by behaviour tests (about 260 retired, 20 kept for release and land fences), and the main source contract shrank from 4 549 to 775 lines.
• Every land now runs an Android Lint gate for API levels, opt-ins, autoboxed state and Compose hygiene; it found and fixed link decoding that silently failed on Android 8-12.
