   BK LABS — v4 « la planche de nuit »
   --------------------------------------------------------------------------
   Direction : le studio se regarde comme une revue. Plein écran nuit,
   respirations claires, typographie énorme, une seule couleur d'action.
   La marque : la grille 3×3 à centre vide — neuf cases, celle du milieu
   est le problème du client. C'est là que le produit vient se poser.

   Trois lettres :
     Archivo (variable, axe de largeur)  → les titres, capitale étirée
     Instrument Serif italique           → le contrepoint, en bas de casse
     Geist / Geist Mono                  → le texte et les repères techniques
