   Styles du guide BIM interactif. Charges uniquement sur /guide-bim
   (front-matter page_css). Tout est scope sous .bim-guide pour ne jamais
   fuir vers le reste du site.
   Repris du module Zyro, nettoye de ses contournements :
     - plus de header fixe duplique (le site en a deja un)
     - plus de --zyro-nav-height
     - plus de bouton retour-haut cree en JS (il est global, voir site.css)
