Issuance (on the proven seam):
- tokens.js create + PUT /:id/targets accept per-playlist zone grants (target_zones), inserted
into api_token_target_zones inside the same transaction as the playlist grants (FK requires
the parent, so order matters and is correct).
- Issuance validation (the mirror of runtime confinement): grantableZoneIds() - can grant ONLY
a zone the playlist's layout actually feeds; can't grant one it doesn't have or one from
another playlist's layout. Bite-tested. PUT re-designate stays atomic: delete parent rows ->
zone grants cascade out (no manual child delete).
- settings.js: checking a designated playlist reveals its grantable zones (GET
/api/playlists/:id/zones, JWT); leave unchecked = whole-playlist. i18n across all 5 locales.
Card:
- GET /api/agency/playlists/:playlistId/layout (rides router.param - confined; a non-
designated playlist -> 403, asserted). "Your zone" = the GRANTED zones. Retired the
token-wide /layouts (the per-playlist card replaces the disconnected lump).
- Portal card reacts to the playlist selector: pick a playlist -> its layout renders, the
granted zone highlighted with px size, siblings as context.
Full suite + agency bite-suite green (154).

So the agency can size/place content: returns the canvas size + zone positions/sizes for the
layouts its designated playlists feed, marking which zones are theirs. DEVICE-FREE BY
CONSTRUCTION - the query path is playlist_items.zone_id -> layout_zones -> layouts and never
touches devices/groups/schedules, so device names/locations/IPs/topology are structurally
absent, not filtered. Geometry only - no sibling-zone content. layout.name included (admin's
canvas name); thumbnail_data omitted (could render other zones' content).
Confinement query in lib/agency-layouts.js, bite-tested: own layout YES, a non-designated
playlist's layout NO, response has NO device fields (asserted on a db where a location-named
device exists), and neutralizing the t.token_id filter goes red. 142 suite green.
