/* ============================================================
   Mega Menu — Meskavan (Gutenberg Navigation block)
   ------------------------------------------------------------
   Turns any submenu of a header nav item into a full-width row
   of brand cards on hover. Desktop only (>=1024px); mobile keeps
   the native Gutenberg accordion untouched.

   Self-contained & transferable: copy this file, enqueue it, and
   (optionally) add the excerpt filter in functions.php. All
   selectors are scoped under .site-header so nothing else on the
   site is affected.
