 * Arcpoly Theme — Components
 * Reusable UI components: button, card, form, badge, modal, tabs, alert, etc.
 * BEM-style naming: block__element--modifier.
 * NOTE: KHÔNG dùng @layer wrapper vì rules ngoài @layer của WP core (block-library,
 * Elementor, WooCommerce default) sẽ ALWAYS thắng rules trong @layer →
 * .btn--brand color bị WP `a { color: inherit }` override → text trắng trên nền
 * trắng/đen-không-đủ-contrast → "empty button" bug. Giờ giữ flat cascade.
