/**
 * QuizTreff Halloween: Premium-Nacht nach der freigegebenen Vorschau vom
 * 05.10.2026. Aktiv über data-theme="halloween" auf <html> (includes/season.php).
 *
 * Die Marke bleibt: Pink und Violett sind weiter die Bedienfarben. Die Saison
 * bringt die gemalte Nacht in den Hero der Startseite, den Boden der Nacht in
 * den Fußbereich, dunkles Glas für Navigation und Karten und warmes Kürbislicht.
 * Die feste Ebene hinter der Seite (Nacht, Nebel, Funken, Fledermaus) steht in
 * season-layer.css.
