/* KI-Plattform - Aufbau wie bisher (Seitenleiste, zentrierte Unterhaltung,
   Nutzer-Nachrichten als Blase, Artefakte als Karte + Split-Panel rechts),
   Erscheinungsbild seit 30.09.2026 nach www.4nes.com.

   Farben und Schrift stehen dort im Elementor-Kit (post-1100.css), am
   30.09.2026 nachgelesen:
     #1C244B Primaer (Navy: Ueberschriften, Knoepfe, Fusszeile)
     #F3F5F8 Sekundaer (Kopfzeile, helle Flaechen)   #F9FAFD Seitengrund
     #324A6D Text   #467FF7 Akzent (Links)   #C8D5DC Linien   #FFFFFF Karten
     Schrift Poppins: Ueberschriften 600, Fliesstext 300, Navigation 400
   Aus dem Logo (4nes-logo-2000px.png): #0A6DAB, #075486, #2E9BD6, #0F1A2E, #6E7F9B.
   Bausteine von dort: helle Kopfzeile mit Logo links und Navigation rechts,
   Navy-Knoepfe mit weisser Schrift, die sich beim Ueberfahren umkehren,
   Navy-Fusszeile, Karten mit 12px Radius, Knoepfe fast eckig (3px).

   Abweichungen, bewusst: Link- und Akzenttext nutzt das Logo-Blau #0A6DAB
   statt #467FF7 - #467FF7 erreicht als Schrift auf Weiss nur 3,6:1. Die
   dunkle Darstellung gibt es auf der Website nicht; sie verteilt dieselben
   Toene auf dunklen Navy-Grund und nutzt das Logo mit weisser Schrift.
   Warn-, Fehler- und Erfolgstoene sind Funktionsfarben, keine Markenfarben. */
