/*
 * shop/css/cart-drawer.css — global slide-in cart drawer + header cart link.
 *
 * Loaded from index.html AND every shop page (via shop.css @import). All
 * rules are scoped to their own .cart-* classes so nothing leaks into the
 * surrounding page. Relies on the brand CSS custom properties defined in
 * the host page's :root (--gold, --bg-card, --border, etc.) — index.html
 * declares them; shop.css redeclares them.
 *
 * No global resets here. This file must be safe to drop into any HTML
 * page without breaking layout.
 */

/* ---------- Nav cart link (inside index.html's existing nav) ----------
 * No display override here — let it inherit the same inline-anchor
 * baseline as the other .nav-links a items, so "Cart (n)" sits flush
 * with Music / About / Gallery / etc.
 *
 * Hide the cart link entirely when the cart is empty. cart.js toggles
 * the `.is-empty` class on .nav-cart itself (and on the inner badge).
