/**
 * Brands index (/brand/) — directory grid + sticky search/alphabet bar.
 *
 * All color / radius / shadow / spacing values come from theme.json tokens so
 * the page stays in lockstep with the rest of the theme. Mobile-first.
 *
 * Layout model:
 *   - ONE continuous grid holds every card; letters are full-width dividers,
 *     so rows stay tight across the whole page (no per-letter half-empty grids).
 *   - The header (title + count + search + alphabet) is a SOLID sticky bar so
 *     nothing floats transparently over the cards. Desktop sticks the whole
 *     header; mobile sticks only the inner search+alphabet bar.
 *   - --rh-header-height is measured + set by brands.js so the sticky offset
 *     sits exactly under the site header (falls back to 64px before JS runs).
