/* ============================================================
   Premium-Bewegung — nur /el/ (griechische Startseite), 26.09.2026

   Gleiche Idee und gleiche Regeln wie premium-el.css auf
   /el/kataskevi-istoselidon/, angepasst an die Bausteine der
   Startseite (dunkler Hero mit Portraet, Preiskarten, dunkle
   Gruende-Sektion). Gesteuert von premium-el.js.

   Regeln (Emil Kowalski):
   - nur transform, opacity, clip-path animieren
   - ease-out fuer alles, was erscheint; nie ease-in
   - Hover nur fuer Maus-Geraete (hover: hover) and (pointer: fine)
   - Buttons geben beim Druecken nach (scale .97)
   - prefers-reduced-motion: keine Bewegung, nur Endzustand

   Alles haengt an body.page-premium-home; die deutsche Startseite
   (gleiche Basis in entwurf-uebernahme.css) bleibt unberuehrt.
   Versteckte Startzustaende nur unter html.js-premium.
