/* ─────────────────────────────────────────────────────────
   Shared grouped header navigation (mega-menu + dropdowns +
   mobile hamburger). Used by the industry pages so the menu
   matches the homepage. Every selector is scoped under
   `.site-header` so these rules win over each page's older
   inline `.site-nav` declarations regardless of source order.
   Behaviour lives in /js/site-nav.js.
