/* --- Darkmode – ohne JavaScript ------------------------------------------
   Kaskade in drei Schritten, alle rein CSS-basiert:
   1) @media (prefers-color-scheme) erkennt automatisch die Betriebssystem-
      /Browser-Einstellung des Besuchers und setzt den Startzustand.
   2) Die Checkbox #theme-toggle im Header (siehe HTML) kann diesen Zustand
      manuell übersteuern – ausgewertet über :root:has(#theme-toggle:checked).
   3) Ist die Checkbox aktiv UND das System bereits dunkel, kehrt der dritte
      Block zurück zu Hell. So schaltet der Regler immer auf den jeweils
      *anderen* Modus um, unabhängig vom Systemzustand.
   Voraussetzung ist :has()-Unterstützung (alle gängigen Browser seit 2023/24).
   Header, Hero, Footer und der blaue CTA-Streifen bleiben bewusst in beiden
   Modi dunkel – sie sind Teil der Marke, nicht des Lesemodus.
