/*
 * Pages d'exemples (refonte du 16 octobre 2026, demande d'Alexandre : « plus dynamique, simple et accrocheur — télécharger un
 * fichier n'est pas accrocheur »). Mêmes repères que l'accueil (1a-accueil.css) : haut BLEU PROFOND quadrillé (`au-hero`),
 * Inter, boutons `au-button`. Trois pages — la liste (deux grandes cartes), la page d'un exemple (le dossier qui se lit en
 * défilant) et la lecture « comme le client » — et rien d'autre. Les mouvements (apparition, tracé du schéma) sont en CSS pur,
 * déclenchés par le contrôleur `home-stage` de l'accueil (is-waiting → is-playing, UNE fois), et absents sous « mouvement
 * réduit » : la page est alors immobile et complète.
