captureAndSend() grabbed a single querySelector('video'|'img') and stretched it
across a fixed 960x540 canvas, so multi-zone Now-Playing screenshots and the 1fps
remote stream showed one zone stretched fullscreen instead of the actual layout.
- Multi-zone layouts now composite each zone from its REAL rendered geometry
(getBoundingClientRect relative to the container, scaled proportionally onto the
canvas), so positions/sizes stay true to the layout.
- Canvas height derives from the container aspect (not a hardcoded 540); media is
drawn honouring its object-fit (cover/contain/fill) instead of being stretched.
- Cross-origin / iframe zones (YouTube, widgets) can't be read back without
CORS-tainting the whole canvas (which makes toDataURL throw and kills the entire
capture). They now get a deliberate, labelled placeholder ("YouTube"/"Widget"/
"Video") so the shot still shows the layout structure with that zone marked,
instead of a transparent hole or a failed capture.
- Split rendering into renderCaptureCanvas() (socket-free, headlessly verifiable)
and captureAndSend() (encode + emit). One full-quality path serves BOTH the
on-demand screenshot and the 1fps stream — the composite is only a few drawImage
calls over already-decoded media, so no separate low-quality stream path.
Web player only; Android (view.draw already composites correctly) untouched.
Verified headlessly on a 3-zone device: red/green image zones render in their
correct positions, the YouTube zone shows a labelled placeholder, and the capture
succeeds with no CORS taint.
