/* Lisse et Cloison Plâtrerie : style « Lisse ». Minimalisme extrême : de très grands aplats plâtre et blancs, filets fins gris pierre, angles droits,
   énormément de respiration, typographie légère (Jost fin, majuscules espacées en surtitres) et précise. L'olive (--accent) vit en aplat avec du texte
   sombre dessus ; le petit texte d'accent est un olive foncé. Jamais d'olive clair en texte sur plâtre.
   Signature : un mur de plaques en SVG, enduit puis poncé par le défilement (voir site.js). */
