The streaming-quality control (Phase 18 wave 18.6, §4) — the first occupant of the Settings menu. Binds
|
|
the listener's choice to PublicSiteSettings.StreamQuality and persists it via the cookie seam. Honest
|
|
capability gate (OQ2 / AC7): on a browser that cannot decode Ogg Opus the Low-data option still selects,
|
|
but a note tells the listener the effective stream is lossless — we never let the choice silently imply a
|
|
format that can't play.
