/* =====================================================================
   VATEC Newsletter - Gestaltungsgrundlage.

   Farbwelt und Maße orientieren sich am Vuexy-Erscheinungsbild
   (violette Primärfarbe, helle Arbeitsfläche, weiße Karten mit weichem
   Schatten, 6 px Radius). Umgesetzt ist das hier eigenständig - es sind
   keine Dateien aus der kommerziellen Vorlage übernommen.

   Drei Zustände beim Umschalten:
     - kein data-theme   -> folgt dem Betriebssystem
     - data-theme="light" -> fest hell
     - data-theme="dark"  -> fest dunkel
   assets/js/theme.js setzt das Attribut vor dem ersten Bildaufbau.
