 * Diamant-Funkeln — kleine animierte Lichtpunkte für Akte + Ticket
 * ============================================================
 * Jeder Funkel ist ein 6px-kleines weißes Lichtpunkt mit Halo,
 * der per JS an einer zufälligen Position eingehängt wird und
 * eine ~1.6s-Animation durchläuft (fade in + scale up + fade out).
 * Nach Ende wird er entfernt und woanders neu erzeugt — so wirken
 * die Funkel verstreut und nie an derselben Stelle.
 *
 * Pointer-events: none, damit Klicks nicht abgefangen werden. */
