/* CHXN component: flying cart — slide-in drawer from the right, replaces
   the standalone /gio-hang/ page in the site's flow. Loaded site-wide
   (add-to-cart can happen from the shop archive, home, related products,
   or the single product page). Markup lives in footer.php; opened/closed
   by modules/flying-cart.js. */

/* ".single_add_to_cart_button.loading" (modules/flying-cart.js's
   setupAjaxAddToCart(), toggled for the whole AJAX round-trip) had no
   THEME css at all for it — but WooCommerce's own core "woocommerce.css"
   already ships a bare, unscoped ".loading{opacity:.25}" rule (plus a
   "::after" spinner using its own icon font, positioned "absolute" with no
   "position:relative" anchor anywhere on this button, so it rendered
   off in a corner instead of visibly on the button) — between the two,
   clicking "Thêm vào giỏ" just quietly faded the button with no visible
   spinner, feeling stuck/unresponsive for the ~1 second the request takes
   (especially noticeable in quick view, which has no other on-page
   feedback the way the single product page still does). Text/icon hidden
   in place (not removed, so the button doesn't reflow/change size) behind
   a proper spinner instead, with WC's own opacity dim cancelled out. */
