   ABEL BUSINESS NEWTECH LLC — feuille de style unique
   -----------------------------------------------------------------------------
   L'identité est dérivée du logo existant : quatre carrés (indigo / gris acier)
   et un sérif Didone. On garde ces deux signes et on construit tout autour :
     · le carré est l'unité graphique (puces, séparateurs, sigle, filigranes) ;
     · Bodoni Moda porte les titres, Inter porte tout le reste ;
     · deux surfaces seulement — papier chaud et encre indigo — alternées.
