/* ==========================================================================
   Zenteria – Liquid Glass Design System (2026)
   --------------------------------------------------------------------------
   Gemeinsame Grundlage für alle Seiten von zenteria.de.
   Aufbau:
     1. Design-Tokens (Farben, Radien, Schatten, Schrift)
     2. Basis / Reset
     3. Hintergrund (Aurora)
     4. Liquid-Glass-Material (.lg)
     5. Navigation + Footer
     6. Komponenten: Buttons, Felder, Pills, Segmente, Callouts, Karten
     7. Hilfsklassen, Animationen, Barrierefreiheit
   Keine externen Schriften/CDNs (DSGVO) – es wird die Systemschrift genutzt
   (SF Pro auf Apple-Geräten, Segoe UI Variable auf Windows 11).
