/* Grafiksystem, abgeleitet aus dem Logo
   Das CI-Manual liefert die Formensprache selbst: der Kreis („O" = Partnerschaft,
   Offenheit) und die drei fortschreitenden Linien („E" = Progression, strategischer
   Weitblick), dazu „Reduktion, Klarheit, Stärke".
   Daraus zwei Bausteine — keine Dekoration, beide tragen Information:
     .axis  Projektachse: die fünf Phasen als Linie mit Punkten
     .span  Phasen-Spanne: welche Phasen eine Leistung abdeckt
