   STYLES V7 (AZURE STATIC WEB APPS)

   Huisstijl volgens claude_huisstijl_spec.js (v3, zwart/wit/groen):
   - Groen       #259F36  accenten, sectielijnen
   - Lichtgroen  #D1FAE5  vlakken
   - Bijna-zwart #111827  koppen en primaire tekst
   - Donkergrijs #374151  lopende tekst
   - Wit         #FFFFFF  achtergrond
   Lettertypen: Montserrat (koppen), Calibri (tekst).
   Calibri is niet vrij te gebruiken op het web; Carlito
   (open licentie, gelijke maatvoering) wordt zelf gehost als
   terugval. Montserrat wordt zelf gehost zodra het bestand in
   /fonts staat; tot die tijd valt de kop terug op een lokaal
   geinstalleerde Montserrat, of anders Segoe UI/Arial.
