/**
 * Premium product gallery.
 *
 * Complements assets/css/woocommerce.css (which sets the 2-col product grid and
 * base .woocommerce-product-gallery styles). This file:
 *   - gives the main stage a consistent 1/1 aspect-ratio box (object-fit:contain
 *     on a neutral --surface ground so mixed-size photos never resize it),
 *   - on desktop turns the gallery into a VERTICAL thumbnail rail (left) + large
 *     sticky stage (right),
 *   - on mobile reflows to a single full-width swipeable stage with a horizontal
 *     thumbnail strip + slide counter.
 *
 * All colours come from CSS custom properties (works in dark & light).
 * Mobile-first: base rules target small screens, desktop rail is layered on at
 * the same 860px breakpoint the product grid uses.
