/* Blaigent Action Cards — tokens + anatomy (hybrid legacy shape)
 * Source of truth: /static/design/action_cards_audit_product.html
 *                  /static/design/action_cards_audit_editorial.html
 *
 * Hybrid design:
 *  - Visual SHAPE = legacy `.action-card` from chat.html (squared,
 *    300px, colored borders, emoji-in-header, labeled rows, footer
 *    helper, receipt meta).
 *  - Feature SET preserved from the new `.act-card` runtime: state
 *    machine, streaming, container queries (widget / mobile-op /
 *    desktop-op), action sheet, sticky approval bar, collapse,
 *    aria-live announcer.
 *
 * Rules:
 *  - Every color/size in .act-* resolves to a token. No literals in
 *    component code.
 *  - Two skins ship. `product` is default. Set data-skin="editorial"
 *    to swap. Renderer produces byte-identical DOM under both skins.
 *  - Same markup for both skins.
