// + CORS hardening
// + ERROR UI SUPPRESSION (hide/clear false “No compatible source…”)
// + AUTO FALLBACK to Progressive (video+separate audio) after repeated errors
//
// Fallback expectations:
//   - Provide progressive **video-only** URL at `window.fallbackVideoUrl` (e.g., MP4/WebM no-audio).
//   - Provide matching **audio-only** URL at `window.fallbackAudioUrl` (e.g., M4A/Opus).
//   - If either is missing, the fallback won’t engage and we’ll keep trying DASH.
//
// The fallback re-enables the old audio+video sync path (single <audio id="aud"> is created if absent).
