/* ===========================================================
   DÉMO — Agence immobilière "Demeures du Nord"
   Archétype VOLONTAIREMENT différent des 3 autres démos :
   "estimation-first" (page tournée vers l'estimation vendeur) +
   grille de biens filtrable côté acheteur. Univers premium :
   vert émeraude + ivoire + laiton, sérif élégant (Marcellus) +
   sans moderne (Manrope). But : prouver qu'on ne plaque pas un
   template unique d'un métier à l'autre.
