   3CH0 — Recherche. Innovation. Protection.
   Palette reprise du dossier de présentation de l'association :
   slate + sky (les valeurs exactes extraites de ses flux PDF).
   Typographies conservées de la charte : Outfit + Plus Jakarta Sans
   (le dossier est en Calibri, police par défaut de PowerPoint — pas un
   choix de marque, donc non repris).

   Contrastes mesurés sur le fond #0F2038 :
     #F8FAFC 15,6:1 · #CBD5E1 10,9:1 · #94A3B8 6,3:1 · #38BDF8 7,5:1
   ⚠️ #0284C7 ne fait que 4,0:1 : JAMAIS en petit texte. Il sert aux
   icônes, filets, remplissages et grands aplats. Tout texte accentué
   est en --sky-text #38BDF8.
   Dans le bloc clair (#F8FAFC) l'accent texte est #1E3A8A (9,9:1) —
   #0284C7 n'y fait que 3,9:1.
