/* ThinkFutureX — Design-System v1.0
   Umgesetzt nach dem Markensystem (Design.pdf, v1.0 · 2026).

   Grundregel: Die ganze Marke lebt auf dunklem Grund.
   Violett ist der Anker (Flaechen, UI, ruhige Akzente),
   Gelb ist das eine Signal (genau ein CTA je Ansicht).
   Mischung: dunkel 70 · violett 22 · gelb 8. Nie beides gleichzeitig laut. */
