/* Hallmark · guihangmy design-system showcase · Floor: chrome colors through system tokens only, no transition:all, focus-visible on every control, reduced-motion fallback, overflow-x clip, sentence-case labels, capped centered container */
 /* Critique: chrome borrows the showcased system itself (.tabs, .card, .btn, tokens) so the page cannot drift from it; waivers: none. */

/* Showcase chrome — everything prefixed .ds- so it never collides with the
   showcased system. All chrome colors come from the system tokens, so the
   chrome itself themes with the switcher. */
