/* ===========================================================================
   KH Variationsauswahl — Popup (Desktop) / Schublade von unten (Handy)
   Gehoert zu frontend/template/kh_variation_popup.tpl und frontend/js/kh-variation-popup.js

   Optik, Abdunklung, Bewegungskurve und Schliessen-Logik sind die der
   vorhandenen Kassen-Schublade (.kh-drawer in NOVAchild/css/custom.css,
   Zeile ~18179): rgba(0,0,0,.45) Abdunklung, weisse Flaeche, Kopfzeile mit
   Trennlinie und grossem ×, 300 ms cubic-bezier(.32,.72,0,1), Scroll-Sperre
   am <body>. Unterschied: am Handy faehrt diese Flaeche von UNTEN hoch
   (Vorgabe Fatih), am Rechner steht sie mittig.

   Eigene Scroll-Sperr-Klasse (kh-varpop-open), damit sie die der Schublade
   (kh-drawer-open) nicht aufhebt, falls doch einmal beides zugleich offen ist.
