Escape </>& in JSON-LD body to kill script-breakout; byArtist now uses the release artist; detail-page not-found branches emit noindex; default robots gated to Production via a PersistentState SeoEnvironment bridge.
One presentational SeoHead renders the full OG/Twitter/JSON-LD head surface at prerender via typed schema.org builders. Per-medium release schema, config-sourced canonicals, 404 noindex. Zero CMS change.
Mint a first-party localStorage anonId, thread it onto play/share beacons,
persist it via EventController, and add all-time distinct-listener counts
(site/track/release). Storage columns + indexes already existed from 16.1.
The queue gains an armed-but-idle state (Arm/Start) so a release embed stages track 0 prerender-safe, then queues the full release on first play and auto-advances.
Compose ReleaseDetailScaffold via Header + BodyContent slots for the Cut
album view: left meta + Play/Share, right theme-bordered cover, TrackNumber-
ordered track list with per-row play. CutDetailBase carries the multi-track
prerender bridge.
