   Präfix kp-. Nutzt die Tokens aus style.css und die Bausteine kx-* aus sections.css
   (Abschluss-Banner .kx-final, Buttons .kx-btn-*, Diagramm .fs-chart).
   Markenfarbe je Projekt kommt als --kp-farbe (Front Matter markenfarbe, Kontrast mit Weiß >= 4,5:1).
   Auf der Markenfarbe stehen weißer Text und ein weißer Fokusring.
