/* ====================================================================
   Couche « Lumen » — accueil
   ====================================================================
   Inspirée du brief de la maquette Dribbble « Lumen – Marketing Agency
   Landing Page » (mise en page audacieuse, visuels dynamiques, parcours
   orienté conversion, preuves chiffrées). Les images de la maquette
   n'étaient pas accessibles : seule sa description l'est, d'où une
   interprétation, pas une copie.

   Règles de la couche :
   - tout se range sous les variables de la charte (style.css) ;
   - aucun contenu n'est masqué sans « js-motion » : sans JavaScript, la
     page reste complète ;
   - tout mouvement est coupé par prefers-reduced-motion.
