+/// Hydrated ticker module state: the current "Aktuelles" post, the filtered
+/// page tree and the slug of the page the user last had open ([selectedSlug],
+/// null = "Aktuelles" home). Persisting the slug lets the ticker reopen on the
+/// last page instead of always falling back to home; a slug that is no longer
