5a — the public watch page rendered every asset in a <video>, but WebKit (all iOS browsers) refuses to play an audio-only mp3 in <video>, so shared audio links were broken on iPad while working on desktop Chromium. public_meta now flags audio-only assets (codec present, no video stream) and WatchPage renders a native <audio> in a padded surface card (no artwork exists for these). 5c — a login-walled Facebook post failed as a bare 'unknown', which offered a misleading Retry. Classify closed-group / cookie-suggestion auth walls as login_required and genuinely unsupported sites as a new unsupported_host class (both non-retryable), and drop unknown from the modal's retryable set — an unclassified failure is most often an unparsed auth wall. The queue row keeps its own force-retry for real transients.
