/* =====================================================================
 *  DIZEN — HEADER MEGA MENU
 * =====================================================================
 *  Loaded on every page via common/head-pwa.php.
 *
 *  Lives in the header now: a "Product Categories" button sits in
 *  .extra-nav, immediately left of Quick Enquiry, and opens this panel
 *  as a full-width dropdown under the main bar. `.main-bar` already
 *  carries `position: relative` (and `position: fixed` once `.is-fixed`
 *  is added for the sticky header) — either way it is a positioning
 *  context, so the panel's `position: absolute; top: 100%` lands right
 *  under the bar with no extra plumbing.
 *
 *  Below 992px there is no room for a rail + columns dropdown, so the
 *  panel becomes a full-screen overlay with a horizontal chip strip
 *  instead of the vertical rail, and the trigger collapses to an
 *  icon-only button.
 *
 *  Everything is namespaced .dzh-*.
 * ===================================================================== */
