BrowsePage accepts pasted or routed channel/playlist URLs:
- Channels get Videos / Shorts / Live sub-tabs mapped to the channel's
/videos, /shorts and /streams listings, lazily fetched 24 at a time
with -I range pagination; channel title and id resolve from a cheap
-I 1:1 metadata fetch. Subscribe emits subscribeRequested for the
Feed page to wire up.
- Playlists get a single grid with Play all (bulk-enqueues into the
Watch queue) and a Download button that deep-links the playlist into
the Downloads tab.
Workers are parented to their pages and fetch errors surface as status
text instead of crashing (verified against a channel with no videos
tab). fetch_flat_info gains an items="1:1" limiter so metadata probes
no longer enumerate whole channels.
Verified live: kurzgesagt channel (24 cards, title+id resolved) and a
17-video playlist with Play-all queueing.
