   PROJET FER — Feuille de style unique (charte v2)
   Site vitrine statique, multi-pages, HTML/CSS vanilla.
   Contenu texte = docx validé client. Aucune dépendance JS externe.

   -------------------------------------------------------------------------
   PORTABILITÉ iPaoo / UIkit (reprise plateforme v3 par Jonathan)
   Chaque motif ci-dessous a un équivalent UIkit direct :
     .section              -> uk-section (+ uk-section-muted pour .section-alt)
     .container            -> uk-container
     .grid-2 / .grid-3 / .grid-4 -> uk-grid + uk-child-width-1-2/1-3/1-4@m
     .pf-btn-primary       -> uk-button uk-button-primary
     .pf-btn-secondary     -> uk-button uk-button-default
     .pf-card              -> uk-card uk-card-default uk-card-body
     .pf-field             -> uk-input / uk-textarea / uk-select
     .site-header (sticky) -> uk-sticky + uk-navbar
     .gallery-filters      -> uk-subnav (filtre) / composant uk-filter
     .lightbox             -> uk-lightbox / uk-modal-full
   Les couleurs, tailles et espacements viennent des tokens --pf-* : il suffit
   de recâbler ces tokens sur le thème YOOtheme pour retrouver l'aspect.
