// #region SmokeE2E [C:4] [TYPE Test] [SEMANTICS e2e, smoke, golden-path, full-stack]
// @BRIEF Golden-path smoke test: login → settings → translate → git → verify.
// @RELATION BINDS_TO -> [E2E.Smoke]
// @UX_STATE FullCycle -> All key user journeys executed sequentially.
// @RATIONALE Single sequential test verifies the entire stack without per-test setup overhead.
//   Runs in ~30s when backend is warm. Mirrors the manual E2E check.
