   Eigenstaendiges Stylesheet. Keine Frameworks, kein CDN.

   Aufbau wie eine Musik-App: feste Seitenleiste links, eigener Scrollbereich
   rechts, durchgehende Abspielleiste unten. Das Theme ist nur dunkel, die Seite
   ist ein Nachtradio. Ein Akzent (Bernstein), eine Radius-Skala, wenige
   Bewegungen, und jede davon bildet etwas Echtes ab.
