/* ===================================================================
   Hans-Albert Färber GmbH — Corporate Website
   Gestaltung: Variante B "Werkstatt" (Stand 22.08.2026)

   Grundsatz zur Farbe: HKS 13 K (#E30018) ist Signal, kein Grundton.
   Rot erscheint nur noch an drei Stellen pro Seite:
     1. primaerer Button (.btn-primary)
     2. das CTA-Farbband (.cta-band)
     3. aktiver Navigationspunkt und Briefbogen-Doppellinie
   Alles Uebrige — Trennlinien, Listenpunkte, Ziffern, Ueberschriften —
   ist Schwarz oder Grau.
