/* ===========================================================================
   Dailies · Audio / Track Review  —  C-level Feed extension
   ---------------------------------------------------------------------------
   A Web Audio track over a decoded waveform that doubles as the timeline.
   The wave is the comment surface: click a moment or drag a range and a note
   anchors to that point/span in time, showing as a marker on the wave so the
   reviewer sees at a glance where feedback lands. The played portion of the
   wave fills gold behind the playhead. A span note can loop on repeat (A-B).
   Threads open in the right rail (a bottom sheet on mobile), mirroring the reel
   review. Self-contained, themed entirely from bsp-tokens.css / dailies-theme.css
   and loaded AFTER feed-styles.css so the .review--audio layout wins the cascade.
