/* I.89.a — Cart drawer + add-to-cart toast.
 *
 * Slide-in panel from the right (desktop) / full-screen (mobile).
 * WCAG AAA contrast against bg-elev-1; respects prefers-reduced-motion.
 *
 * The drawer pins its own color scheme (dark surface + light text) so it
 * looks consistent across light/dark page themes. The storefront CSS
 * variables (--bg-elev-1, --text-primary) switch with the OS theme, but
 * the drawer is a transient overlay and reads best with a fixed
 * surface contrast.
