/*
 * Header + Footer — Template 2.
 *
 * Auto-loaded via inc/fn-setup-css-js.php glob (assets/css/t2/*.css).
 * Currently glob loads ALL t{N} CSS — when conditional enqueue lands,
 * this file should only load when hf_template_variant === 't2'.
 *
 * Brand color: T2 primary #ff2881 (xanh hồng), exposed via --iw-accent
 * which scheme can override (decoupled from H/F variant).
 *
 * Convention: every class carries its own values — no dependency on
 * body class / parent wrapper / site-level CSS vars (except --iw-accent
 * for theme color tokens).
