galaxy-game/ui/frontend/tests/e2e/order-sync.spec.ts

// Phase 25 end-to-end coverage for the sync protocol additions on
// the order tab: the offline / online flip, the
// `turn_already_closed` conflict banner, and the `game.paused` push
// frame. Each test boots an authenticated session, mocks the lobby
// + report + order routes, drives an order mutation through the
// inspector, and asserts the matching banner / sync-status DOM.
