/* ==========================================================================
   Franklin Core – Feature Enhancements
   Neue, seitenübergreifende Funktionen: Onboarding-Tour, Hell-/Dunkelmodus,
   Sprachumschalter. Wird auf allen Unterseiten zusätzlich zu shared.css und
   chat-widget.css eingebunden und überschreibt gezielt (mit !important) die
   vorhandenen Tailwind-Utility-Klassen für den Hellmodus, ohne shared.css
   selbst anfassen zu müssen.
