/* =====================================================================
   Nadawis Tech — feuille de style unique du site V1
   ---------------------------------------------------------------------
   Palette : charte de marque NADAWIS Technologies v1.0 (14/08/2026),
   au chiffre près. Aucune couleur inventée.

   Règle d'emploi issue du calcul de contraste de la charte :
   la terre cuite #A65A3A ne descend PAS à 4,5:1 sur le beige minéral
   (3,81:1). Elle n'est donc jamais du texte courant : elle est un fond
   de bouton (blanc dessus = 5,07:1), un filet, une puce, un grand titre.

   Typographie : aucune police distante. Le couple Georgia / sans-serif
   système est celui du document de charte, où la typographie officielle
   est encore marquée « à confirmer ».
