- 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.
New GET /api/channels/activity returns subscribed channels sorted by
their latest video (no-video channels last) with the 3 newest videos
per channel and cursor pagination. The feed page gains a 'Лента |
Каналы' toggle (?view=channels) with compact video cards per channel
row; category filters and the sidebar preserve the view.
