 * Design-token-first — all colours via CSS custom properties from src/index.css.
 * No one-off hex values.
 *
 * Layout:
 *   ≥601 px  — anchored popover above/below the trigger
 *   ≤600 px  — full-width bottom-sheet with slide-up animation
 *
 * prefers-reduced-motion: all transitions/animations removed.
