// Smoke test for the Beta UI banners. Verifies the
// non-production-ready banner appears in both supported locales.
//
// Does NOT call into the FRB Rust side; that requires the cdylib at
// runtime and is verified by alpha_e2e_test.dart + beta_e2e_test.dart.
//
// Requirement trace (SWE.4 unit verification — banner widget):
//   SRS-165..SRS-169 (localization), SRS-170..SRS-176 (Unicode / server content),
//   SAD-014 (design-system + localization integration),
//   SDD-031, SDD-032, SDD-033, SDD-034 (localization fallback + product-vs-server text).
//   Verification-plan rows: SWE4-UV-014, SWE4-UV-019, SWE4-UV-020 (swe4-unit-verification-plan.md).
