   COMPONENT: product-card.css
   Aliyan Collection - product cards + product grids.
   Used on: home (new arrivals), shop pages, search results, wishlist,
            related products. Cards are built by js/components/product-card.js
   ---------------------------------------------------------------------
   Two card layouts are supported (same class names as the old site):
   A) HOME / SEARCH card
        .product-card > img + .product-info (h4, .price, .btn.add-to-cart)
   B) SHOP card (hover action bar)
        .product-card > [.sale-tag] + a.product-link (img + .product-info)
        + .product-actions (.action-btn.add-to-cart / .add-to-wishlist)
   Grids:
        .product-grid            -> home / search / related
        .product-grid-listing    -> shop pages (.col-2 .col-3 .col-4 .col-list)
