cc_load_policy is only a request: the viewer's "always show captions"
preference overrides it, and auto-generated tracks ignore it. Unloading
the caption module is the part that sticks, and it has to run again after
every load because a new video brings the module back.

Two frontends sharing one WebSocket-backed state on the server:
- Player: fullscreen poster background with a small frame (30% of the
screen) that drifts diagonally and reflects off the edges. Two stacked
YouTube players hand over with a 5s equal-power crossfade so there is
never silence between tracks.
- Queue: add by URL, drag to reorder, delete, click to jump. Shows title
and length per item, highlights what is playing, and tracks remaining
vs. total playtime.
No API key is required — titles come from YouTube's oEmbed endpoint and
durations from a hidden muted probe player that cues each new video just
to read its length.
The fade is driven by both requestAnimationFrame and the interval tick:
a hidden or throttled tab stops serving frames entirely, which would
otherwise strand a handover half-faded with two tracks audible.
