/* tog.zone — Designsystem.
   Sommerliche Fassung. Grundsätze unverändert: keine abgerundeten
   Ecken, ein Verlauf für Seitenköpfe, weiche farbige Schatten.

   Vier Farbrollen, damit nichts durcheinandergerät:

   Sonne   — der Verlauf und alles Verlinkte. Das frische Orange trägt
             die Seite, wo früher Blau stand.
   Ton     — dunkles Orange für Navigation und dunkle Flächen.
   Aktion  — Natur-Grün. Nur, was der Nutzer auslöst: Primärknöpfe.
   Warnung — Rot bleibt Rot. Ein grüner Löschknopf wäre eine Falle. */
