/**
 * Case-notes gallery — stage + thumbnail strip.
 *
 * Every value is a design-system token. The reference build inlines raw hex and
 * pixel values on each element; that renders the same and cannot be re-themed.
 *
 * The block is left untouched until the script replaces it, so with JavaScript
 * off nothing here applies and WordPress's own gallery grid stands.

/* Breathing room from the copy above and below (client, 31 Aug 2026).
   Asked for 30/20; taken from the spacing scale instead, on the client's word —
   26.7/20 at 1440, shrinking to 20/16 at 360, so the gap stays proportionate on
   a phone where a fixed 30px would not. Applied to the un-enhanced block too,
   so the no-JavaScript fallback is spaced the same. */
