   Flow Studio : feuille de style (direction « verre dépoli »)
   Palette : crème #F6F5EF · vert profond #173C3B · vert clair #C6EC91
   Contrastes vérifiés (WCAG AA) :
     #173C3B sur #F6F5EF ≈ 11:1     ·   #C6EC91 sur #173C3B ≈ 9:1
     #B9C6C3 sur #173C3B ≈ 6,8:1    ·   #4A5E5D sur #F6F5EF ≈ 6,3:1
   Les surfaces de verre qui portent du texte restent assez opaques
   (≥ 72 % de vert, ou ≥ 62 % de crème) pour garder ces contrastes
   quelle que soit la photo en dessous.
