+ * Used by `NextStepCard`, `SetupChecklist`, and `QuickStartPage` so the toggle
+ * row can disappear when there's nothing to show. Each consumer has its own
+ * state — fetches are not deduplicated. That's fine for now; if it becomes a
+ * problem we can lift this into a Zustand store or react-query.
