/* dashboard.kaikas.net
   Design uebernommen von expert.kaikas.net: weisser Grund, ein Akzentblau,
   Systemschrift, 6px Radien, Trennlinien statt Kaesten. Ergaenzt um die Rollen,
   die ein Dashboard zusaetzlich braucht (Kacheln, Diagramme, Status).

   Die Serienfarben sind eine validierte kategoriale Palette mit dem Akzent der
   Seite auf Platz 1 — geprueft auf Helligkeitsband, Buntheit, Farbfehlsichtigkeit
   und Kontrast, in hell wie dunkel. */
