/* SweetPixel Werbebanner – flüssiges Glas (Version 1.1.0, 05.11.2026)
 *
 * Ablauf: Ein Glastropfen fließt von rechts unten (außerhalb der Seite) herein, wabert, dehnt sich zum Glasfenster
 * und bleibt unten rechts stehen. Der Rahmen ist ein langsam fließender Farbverlauf, das Fenster "atmet" leicht.
 * Schließen: Inhalt verschwimmt, das Fenster zieht sich zum Tropfen zusammen und fließt nach rechts unten hinaus.
 * Alles reines CSS (keine Bibliotheken). Mit "Bewegung reduzieren" im System: nur sanftes Ein-/Ausblenden.
