   Hell / Weiss mit Akzent Orange

   Performance-Hinweis: Es werden bewusst keine filter: blur() Flächen und
   kein backdrop-filter animiert. Grosse weichgezeichnete Ebenen müssen bei
   jedem Scroll-Frame neu gerastert werden und das war die Ursache für das
   Stocken. Die Farbstimmung entsteht jetzt über statische radial-gradients,
   die der Compositor einmal zeichnet und danach nur noch verschiebt.
