/* Ballauff Haustechnik GmbH — Website-Stylesheet.
   Farbgrundlage: Firmenfarben Rot #cc2c24 (RAL 3028), Gelb #f6b600 (RAL 1021), Anthrazit/Schwarz.
   Kontrast geprüft (WCAG): Rot auf Weiß = 5.32:1 (AA Fließtext bestanden) → als Text-/Button-Farbe nutzbar.
   Gelb auf Weiß = nur 1.81:1 (durchfällt) → Gelb NIE als Text/Linie auf hellem Grund, nur als Fläche
   mit schwarzem Text (11.6:1, AAA) — das Muster der Firmenbroschüre für ihre Tätigkeitsfelder-Boxen. */
