/**
 * Cart Drawer — premium jewellery cart panel.
 *
 * EVERY rule here is scoped to .cart-drawer. The base drawer styles in
 * menu-drawer.css (.opsim-drawer, .drawer-overlay, .drawer-content,
 * .drawer-header, .drawer-close) are shared with the menu drawer and the
 * categories drawer, so overriding them unscoped would restyle both. The
 * heavy black header and the 50%-opacity page overlay come from there and are
 * neutralised for the cart drawer only.
 *
 * Visual identity matches the product card (product-card.css): warm ivory
 * image ground, hairline borders, var(--opsim-radius), ink type, brand colour
 * reserved for the CTA. Item rows are separated by hairlines rather than boxed
 * into cards — lighter, and it stops the panel reading as a stack of tiles.
 *
 * Markup contract used by assets/js/modules/cart.js (do not rename):
 *   #opsim-cart-drawer, .is-active, .is-loading, .drawer-overlay,
 *   .drawer-close, .cart-item[data-cart-key], .cart-item-remove,
 *   .qty-btn[data-action], .qty-input
