   ERP logistique B2B : négoce bois / palettes / transport.
   ---------------------------------------------------------
   Ce qui est CONSERVÉ d'Akiwi  : la grammaire complète
   (noms de tokens, échelle typo 14px, grille 4px, rayons,
   ombres, classes de composants, dark mode [data-theme]).
   Ce qui est ADAPTÉ à Prima    : neutres froids (opérationnel
   plutôt qu'éditorial), primaire pétrole, signature ambre
   (bois/énergie), 4 couleurs de pôles métier, densité de
   tableau resserrée pour l'Order Book.
