/* ============================================================
   RF INVESTMENTS — Kaufbeuren — Design-Entwurf
   Palette: tiefes Marineblau/Schwarz + Champagner-Gold — nüchterne,
   seriöse Private-Banking-Optik, bewusst ohne Deko-Elemente (kein
   Chart-Schmuck, keine Farbverläufe). Bildfrei (keine echten Fotos
   verfügbar, keine Stock-Berater-Bilder). Bewusst schlank gehalten:
   die Quelle lieferte fast ausschließlich unbearbeiteten WordPress-
   Theme-Demotext, keine echten Leistungsdetails — Substanz kommt aus
   klar strukturierter Erreichbarkeit statt erfundenen Leistungen.
