/* OH Immobilien – Gestaltung
   Grundsatz: viel Luft, feine Linien, Serifen-Überschriften, keine Verläufe, keine Schatten,
   keine Icons in Kreisen. Grün als Rahmen, Weiß und Creme für Inhalt, Gold als feiner Akzent.
   Bewegung nur leise: Einblenden beim Scrollen, sanfte Übergänge, nichts, was blinkt. */
