/* ==========================================================================
   IT-Messner
   Grundlage ist die erste Fassung der Seite: hell, luftig, zentrierter Hero
   mit Netzgrafik, Karten mit weichen Ecken, Pillen-Buttons, dunkler
   Kontaktblock. Überarbeitet nach impeccable: keine Eyebrows, keine
   Icon-Kacheln über Überschriften, keine gleichförmigen Kartenraster,
   eine selbst gehostete Schrift statt der Systemschrift.

   Farben kommen aus dem Logo (README-Logo.md):
   Blau #2563EB, Türkis #0D9488 (nur Grafik), Tinte #0F172A, Schiefer.

   Die Seite ist bewusst immer hell. Es gibt keinen automatischen
   Dunkelmodus mehr; color-scheme: light verhindert auch, dass Browser
   die Seite eigenmächtig abdunkeln.
