/* Air Market - v6 collections (W5).  Paired JS: assets/js/v6/collection.js.
   Every rule scoped under :root[data-v6="on"] - see store-v6-core.css for the
   layer-flag contract. Tokens only, cursors via var(--cur-*), no hardcoded hex,
   no U+2014.

   Mobile-first by function: the collection page is the second most-shared object
   in the store and it is opened from a phone (§14). It is a reading surface, so
   it is a single centred column that the cards fill, not a grid.

   The .v6-card* family (collection tile, creator chip) is rendered by V6.card.*
   in core.js and is core's to own; store-v6-core.css ships empty in this build,
   so the minimal finished styling lives here, where these cards are shown. */
