/* ═══════════════════════════════════════════════════════════════════════
   ERP365 — feuille de style unique (Control Plane + site marketing).
   Pas de framework, pas de build : une seule requete, lisible et modifiable.

   DIRECTION : panneau d'instrumentation. Le produit sert a lire l'etat reel
   d'une infrastructure ; l'interface emprunte donc son vocabulaire visuel aux
   panneaux de controle — surface anodisee, etiquettes serigraphiees en
   capitales condensees, voyants carres, identifiants en chasse fixe.

   ELEMENT SIGNATURE : le « couple d'etats » (.pair). Tout le produit repose
   sur l'ecart entre etat DESIRE et etat REEL. Partout ou ce couple existe, un
   rail relie les deux valeurs : continu quand elles concordent, decroche et
   colore quand elles divergent.
