/* ==========================================
   SalmasFlix — Sync Player · Partner position marker
   Extracted from media.css in Phase 7.4.

   The small circular avatar that rides the scrubber at partner's current
   playback time when I'm in Alone mode. Tap → snap my player to their
   position via `_snapToPartner()`. Disney+ GroupWatch convention
   ("always see who is controlling") ported to the scrubber axis.

   Position is driven by `--ppm-pct` (set each tick by `media.js
   _updatePartnerMarker()` at 500 ms cadence; projects partner's time +
   (now − lastUpdate) between server pushes so the avatar slides smoothly
   while partner is playing). `hidden` attribute hides the marker when
   I'm in Together mode, when partner is on a different item, or when
   duration is unknown.

   Secondary color (var(--secondary)) matches the Alone pill in the
   sync-role capsule — "secondary = decoupled / independent" is the
   consistent signal across the whole sync UI.
