/* ==========================================================================
   BASCULE — direction artistique « le relevé »
   Le site se lit comme le dossier d'un bureau d'études : papier clair, encre
   noire, filets fins. Trois couleurs prises au sujet lui-même : le jaune du
   soleil pour l'action, la terre cuite des tuiles pour la facture d'aujourd'hui,
   le bleu des panneaux pour celle d'après. La photo aérienne est montrée à
   plat et cotée, comme un relevé ; l'économie tourne sur un compteur à roues.
   Aucun dégradé décoratif, aucun halo, aucun effet de verre.
