- Detect shorts by duration (SHORTS_MAX_DURATION_SECONDS, default 180)
and expose is_short in feed, video and channel-activity DTOs.
- Feed gains type=all|long|short and anchor; lists show a two-mode
'Обычные | Shorts' filter (no 'Все') persisted in the URL.
- Clicking a short opens /shorts/🆔 a vertical scroll-snap feed with
autoplay for the active slide, context-aware endpoints and infinite
loading.
- Keep the sound choice across swipes, syncing with the player's own
mute control and guarding against the widget's stale isMuted() reads.
