/* =========================================================================
   NESU DIGITAL — feuille de style unique.

   PALETTE. Le fond est un BLANC, mais un blanc accorde au logo : jamais du
   #FFF pur sur toute la page, qui virerait au bleu a cote du vert de marque.
   Les surfaces alternent entre le blanc franc des cartes et un blanc tres
   legerement teinte de vert (#F7FAF9), pris dans la meme famille que le logo.

   L'OR NE PORTE JAMAIS DE TEXTE COURANT. Sur blanc il plafonne a 2,2:1, tres
   en dessous du seuil de lecture. Il sert de trait, de chiffre et d'accent
   graphique ; quand il faut de l'or lisible, c'est la LUMINOSITE qui est
   corrigee et la teinte qui est conservee.
