/* ==========================================================================
   PTI — v2 mega-menu (Phase 3)
   Markup comes from pti_mega_nav() in functions.php. Panels open on hover and
   keyboard focus with CSS alone; pti-v2-menu.js adds click/tap toggles,
   Escape, outside-click closing and the current-section highlight.
