   WISY SAFETY — Gabarit « fiche technique » des pages formation
   (formation-vca-ligne-hierarchique.html · formation-diisocyanates.html · formation-fibre-optique.html)
   -------------------------------------------------------------------------
   Une formation se lit comme un document de référence : sections numérotées (01, 02…), filets fins, sources visibles
   en fin de section, très peu de cartes, aucun effet décoratif. Chaque fiche ajoute sa direction artistique
   (css/fiche-*.css, voir « Thèmes de fiche » en fin de fichier). Tokens : ceux du socle de chaque page (:root).
   Préfixe unique `fx-` : rien n'entre en conflit avec les autres pages. Propriétés logiques (RTL arabe).
