/* ============================================================================
   Theme "register" – Umsetzung des Claude-Design-Konzepts (Redesign 2026).
   Gestaltungssprache: warmes Papier, Tinte, Petrol als einziger Akzent,
   1-px-Linien statt Flächen und Schatten, Archivo (variabel, breit) für
   Auszeichnung, IBM Plex Mono für Daten, Nummern und Meta-Zeilen.

   Abweichung vom Entwurf mit Absicht: Die Textfarbe #8b9297 aus dem Konzept
   erreicht auf dem Papierton nur 2,7:1 und faellt bei WCAG AA durch. Fuer
   Text gilt darum --ink-40:#5f686e (4,97:1); #8b9297 bleibt reinen
   Dekorlinien vorbehalten. BFSG geht vor Pixeltreue.
