// Integration test for the Phase 14 optimistic overlay. Mounts the
// inspector tab against a real `OrderDraftStore` + `GameStateStore`
// + the rendered-report context and walks the full happy path:
// add a `planetRename` command → mark it submitting → applied → the
// inspector picks up the new name through the overlay without a
// re-fetch of the report.
