/* ── WordPress admin bar compatibility ────────────────────────
 * Admin bar is position: fixed at viewport widths > 600px (admin-bar.css:94, 1118-1121).
 * WordPress sets --wp-admin--admin-bar--height on html:
 *   783px+  → 32px  (admin-bar.css:2)
 *   782px-  → 46px  (admin-bar.css:784-787)
 * At ≤ 600px the admin bar becomes position: absolute (scrolls away),
 * so no offset is needed; this rule only fires at min-width: 601px.
 * body.admin-bar is added by WordPress only when the user is logged in
 * and the admin bar is showing — visitors are unaffected.
 * The mobile nav panel (.zzl-site-nav, position: absolute relative to
 * .zzl-site-header__inner) moves with the header automatically; no change needed.
 * ──────────────────────────────────────────────────────────── */
