/* ============================================================
 * DRC Resistor T-Shirt — /products/drc-resistor-t-shirt
 *
 * Ported from the handoff drc-tee.css. Global tokens, nav, footer, .btn and
 * the light-theme block already live in public/style.css; this sheet
 * carries the merch-PDP chrome only. `.section` / `.sec-head` / `.kicker`
 * are (re)defined here for this page's local look — this sheet only loads on
 * this page, so it doesn't affect the global versions elsewhere.
 *
 * Differences from the handoff: the gallery cells hold real <img> (not the
 * <image-slot> mock), and the add-to-cart toast is dropped — the shared nav
 * cart popup is the add feedback instead.
 * ============================================================ */
