/* ============================================================================
 * Pershume — shop archive + brand taxonomy (MOBILE-FIRST).
 *
 * Enqueue ONLY on the product listing pages (is_shop() / is_product_category()
 * / is_product_taxonomy() / is_tax('product_brand')). Loads AFTER style.css and
 * woocommerce.css and OWNS the whole archive + brand layout, so it reuses the
 * :root tokens from style.css (--accent / --ink / --line / --gut / --radius …).
 *
 * Authored mobile-first: the base rules target a ~390px phone (80% of traffic);
 * min-width media queries scale up to tablet (2-col) and desktop (3-col, sticky
 * sidebar). Every grid uses minmax(0,1fr) so cards never force overflow.
 * Class names match the markup emitted by inc/template-functions.php so the
 * existing drawer / collapse / chip JS in theme.js keeps working untouched.
