/* =========================================================================
   Chatbot-Verwaltung — Gestaltung nach der Designsprache von
   webdesign-zoning.de (Farben, Radien, Schatten, Schriften aus css/styles.css).

   Zwei getrennte Farbwelten, bewusst:
   - Oberflaeche: die Markenfarben (Dunkelblau #1b2c50, Rot #b23f42).
   - Diagramme:   eigens gepruefte Datenfarben. Das Markenblau faellt als
                  Datenfarbe durch die Pruefung (zu dunkel, zu grau) — als
                  Balken auf hellem Grund waere es nicht unterscheidbar genug.
                  Geprueft mit dem Palettenpruefer: hell #2f5aa8 / #b23f42,
                  dunkel #5b8ad4 / #d06b6e (Helligkeitsband, Chroma,
                  Farbfehlsichtigkeit, Kontrast — alle bestanden).
