The /nowplaying handler called source.duration/source.elapsed on the live
crossfaded source. Since it is polled every second by the web player, those
cross-thread source queries contended with the crossfade's own clock during a
transition and wedged the streaming clock — a few seconds of audio then a
frozen buffer looping on air, only ever with a listener connected.
Capture duration and the track start time in a synchronous on_metadata
callback (which runs in the clock thread, where touching the source is safe)
and have /nowplaying read those refs instead — position is just the wall-clock
time since the track started. No handler touches the source outside its clock
anymore, so the 3 s crossfade is safe again.

The web player decides when a track counts as listened (caught near its
start and heard to ~90%, capped at 4 min) and triggers POST /scrobble.
The token stays server-side (RADIEO_LISTENBRAINZ_TOKEN), submitting the
listen with the canonical MusicBrainz MBID when available. Each airing is
deduplicated so multiple tabs submit it once.

Extract the HTTP surface out of radio.liq into two included files: web.liq
(static assets, PWA, local player API) and ingest_proxy.liq (relays to the
ingest daemon). radio.liq keeps only the streaming pipeline and ends with the
%include directives, evaluated after the pipeline so the handlers see radio,
now_playing, history, etc.
