video downloads (phase 2): unified video quality profile
One profile across slskd/torrent/usenet — video quality is resolution + source +
codec (parsed from the release name/filename), not bitrate. Best-in-class settings UI
on the video Downloads tab:
- resolution tiers (4K/1080p/720p/480p) with per-tier toggle + arrow reordering
(priority best-first), pill toggles
- source preference (BluRay > WEB-DL > WEBRip > HDTV), reorderable
- codec segmented control (Any / x265 / x264), Prefer-HDR toggle
- max-size-per-item slider (0 = no limit) + lower-quality fallback toggle
core/video/quality_profile.py: pure default/normalize/load/save (clamps size, rejects
bad codec, dedupes source list, recovers from corrupt JSON) — stored as JSON in
video.db's video_settings['quality_profile']. GET/POST /api/video/downloads/quality.
video-settings.js renders + saves it; isolated from music (imports only json/typing).
11 tests (9 pure + 2 API). Next: video source-mode + hybrid, then the shared slskd block.
