/*
 * Héros-diaporama partagé des pages publiques (macro App/Views/vitrine/_hero.php), chargé après site.css.
 * Modèle : l'Espace numérique (external/ent.php). Moteur : js/scripts/connexion-slider.js (contrat .sx-ls-*),
 * aucun script propre. Scènes : vitrine/_hero-scenes.php (+ external/_ent-scenes.php).
 * 1. .sx-eh   héros en carrousel (variante .is-compact pour /demo)
 * 2. .sx-rib  rangée statique de mots-clés (puces qui passent à la ligne, aucun mouvement)
 * Mobile d'abord (360 px). Sans JavaScript : diapositives empilées et lisibles, seule la première scène affichée.
 * Animations : transform, opacity et stroke-dashoffset seulement ; coupées par prefers-reduced-motion
 * (règle globale de site.css + aucune lecture automatique côté moteur).
 * Couleurs : jetons --sx-* de site.css uniquement (les rgba reprennent les mêmes teintes).
