/* =====================================================================
   APG Header + Mega-Menue  ·  Phase 1  ·  TAB-BASIERT (Tims Artifact)
   ---------------------------------------------------------------------
   Verbindliche Vorlage: Artifact „PRANA Systeme — Mega-Menue Vorschau".
   Fruehere flache Multi-Spalten-Variante = verworfen.

   - ALLE Selektoren unter .apg-nav gekapselt -> keine Nebenwirkung auf
     den Live-Header (Elementor bleibt unangetastet).
   - Design-Tokens 1:1 aus dem Artifact, lokal auf .apg-nav gesetzt.
   - Panel: 3-Spalten-Grid 25fr / 40fr / 35fr, column-gap 34px,
     max-width 1240px. Titel 17px / Text 15px einheitlich.
   - Tab-Wechsel per JS (click + mouseenter); Desktop-Open per Hover +
     Klick-Toggle. Mobile <=960px: Burger-Drawer, Mega = 1-Spalten-Akkordeon.
