 * DÉCORATION — halloween : braises, toiles d'araignée, citrouilles et chauves-souris flottantes

 * Chargée seulement si l'option « Décorations » est cochée dans l'admin.
 * Purement visuelle : ne bloque aucun clic (pointer-events: none), s'arrête si l'utilisateur
 * a demandé moins d'animations, et reste sous les fenêtres modales.
