/* ========================================================================
   KarPayı — Mega Menu (lazy)
   Universal, domain-agnostic desktop mega menu foundation.

   Load AFTER foundation.css + app.css; loaded only on layouts using
   the public main-nav (public.html.twig). Mobile (< lg) hides the
   panel entirely — mobile drawer owns < lg navigation.

   BEM family: `kp-mega-menu__*`.
   Slots: trigger, sidebar, content, aside, footer, placeholder.

   Contract: design-system-agreement.md §13 Mega Menu Contract.
