   Lien Concept — systeme de design
   --------------------------------------------------------------------------
   Parti pris : Lien Concept fabrique des volumes en bois et en metal, et les
   eclaire. Le site emprunte donc aux catalogues d'atelier et aux portfolios
   de scenographie, pas aux gabarits SaaS : angles vifs, filets fins, index
   numerote, tres grandes capitales, alternance de registres sombre / papier.

   Trois choses volontairement absentes, parce qu'elles signent le site
   generique : le degrade violet, le verre depoli, et la rangee de trois
   cartes arrondies identiques.
