/* onlinestern.de: Gestaltung "Leitstern".
   Hell, farbig, präzise. Eine Display-Schrift mit Charakter (Bricolage Grotesque),
   eine ruhige Leseschrift (Inter). Der vierzackige Stern ist das einzige Schmuckelement:
   Marke, Aufzähler, Fortschrittsmarke im Anfrage-Assistenten. Alles andere bleibt still. */
