// Phase 24 end-to-end coverage for the push-event path. Boots an
// authenticated session, mocks the gateway calls the in-game shell
// makes (`lobby.my.games.list`, `user.games.report`), and serves one
// signed `game.turn.ready` frame on the `SubscribeEvents` stream.
// The test asserts the toast surfaces with the new turn, the action
// button advances the store onto the new turn, and the header
// reflects the freshly-loaded snapshot.
