/* css/action-picker.css   (Phase C, 2026-05-23)
 *
 * Visual icon-gallery for per-tile Actions. Companion to
 * /js/builder/action-picker.js. Designed for 5-year-old usability —
 * each action tile is large (min 44px tap target × actually ~120×120),
 * has a chunky emoji icon, a short label, and a one-line description.
 *
 * Disabled states ("Coming soon" for phone/sms/email) are dimmed +
 * NOT clickable, but still tab-stop accessible so screen-reader users
 * hear the disabledReason via aria-label.
 *
 * Re-uses .modal-overlay / .modal classes from builder.css so the
 * BottomSheet primitive's `innerSelector: '.modal'` (we override to
 * '.action-picker-card' on attach) sizes correctly for keyboard-aware
 * mobile UX.
 *
 * LABEL: PILOT-READY — needs iOS Safari + Android Chrome hardware
 * verification on the icon-grid tap targets before PRODUCTION-READY.
