"""Son — Phase 6 du plan d'extension du moteur : musique de fond par écran
(en boucle, suit le cycle de vie de l'écran) et action ponctuelle "Jouer un
son" (effet sonore, non bouclé). Comme le reste du graphe de logique côté
client, la lecture audio RÉELLE n'est pas testable sans navigateur (voir
play_js_bundle() — on vérifie que la logique existe dans le JS livré et que
les données persistent, pas qu'elles jouent un son)."""
