/* ==========================================================================
   XBuild — Auth-Template (Login / Registrierung)
   Neues CI · Split-Screen · SaaS-Standard
   --------------------------------------------------------------------------
   Übernahme durch David:
   - Diese Datei einbinden (oder Inhalt inline in den PHP-Echo ziehen).
   - Fonts: Heebo (Display) + Inter (Body) — wie Website. Google-Fonts-Link
     steht in den HTML-Dateien; alternativ selbst hosten.
   - Farben zentral als CSS-Variablen unten — 1:1 aus dem Website-CI.
   - Reine Präsentationsschicht. Keine Logik. Formular-action + Feldnamen
     bleiben wie im Bestand (siehe Kommentare in den HTML-Dateien).
