// Phase 11 end-to-end coverage for the live map integration. Boots
// an authenticated session through `/__debug/store`, mocks the two
// gateway calls the layout makes (`lobby.my.games.list` and
// `user.games.report`), navigates to `/games/<game-id>/map`, and
// asserts the chrome reflects the live data: turn counter shows the
// reported turn, the map view enters its `ready` state with a
// non-zero planet count, and a zero-planet response renders the
// empty world without errors.
