/* Diagnostic sans barrière (ticket #251, maquette validée par Anthony le 28/10/2026 : docs/maquettes/diagnostic-2026-10-28.html).
   Univers de la vidéo Flow V4 (design system Runflow › Mouvement et vidéo). Feuille dédiée aux pages /diagnostic et
   /diagnostic/resultat : /webinaire et /diagnostic/donnees gardent campagne.css. Aucune couleur écrite ici : tout passe
   par les jetons de /jetons.css (chargée avant), le vert Relais (--rf-relais) seulement pour le trait sur sauge.
   Mondes : accueil = nuit (ivoire en clair) ; questions = forêt (sauge en clair) ; passage = plaque citron fendue à la
   pente du logo ; résultat = chiffre sur citron, priorités sur nuit ou ivoire, « Et maintenant ? » sur forêt.
   Angles vifs partout. Animations coupées sous prefers-reduced-motion. */
