+/// Covers the "Danger Zone" purge UI's warning-dialog gating, now folded
+/// into the Settings > Data > Advanced section — the actual delete behavior
+/// (soft-delete tombstones, dirty flags, receipt file cleanup) is covered
+/// against a real database in purge_data_test.dart. This deliberately never
+/// taps a dialog's destructive "Delete" button: doing so would call through
+/// to [AppState.purgeAllData]/[AppState.purgeFuelEntriesInRange], which need
+/// an initialized database — not set up here, matching every other Settings
+/// widget test (see theme_toggle_test.dart) that stops short of a full
+/// [AppState.init].
