/* ============================================================================
 * Endplay client styles — the warm "sticker" skin (A12 front-end redesign).
 *
 * Design system reconciled from docs/design/DESIGN_HANDOFF.md + the reference
 * build (docs/design/Endplay.dc.html). Accessibility is a requirement, not
 * polish (audience: older adults on a phone):
 *   - All copy/UI type in rem, root font-size never pinned -> honours the OS
 *     text-size setting AND the in-app Text size control. (Chips are fixed
 *     graphical tokens >= 44px; their dark digit passes WCAG AA on every fill.)
 *   - Suit carried by SHAPE as well as colour, always on, everywhere suit shows.
 *   - Touch targets >= 44px. prefers-reduced-motion respected.
 *   - Theme is three-state: light (bare :root), dark (media + [data-theme]).
 * ========================================================================== */
