# Issue #278 Artifact — smoke/e2e gate for da+en locale flow and primary-only audio

## Scope
Acceptance for `[READY][#175][P4]`:
1. Verify one MVP host+player smoke run in `en`.
2. Verify one MVP host+player smoke run in `da`.
3. Verify audio routing remains `primary-device only` so phone/player clients never take playback ownership.

Dette er en gate-/evidensleverance. Ingen ny produktfunktion ud over test/verifikation.

## Implemented smoke gate
Angular smoke spec: `frontend/angular/src/app/i18n-mvp-flow-smoke.spec.ts`

The gate now runs two explicit locale scenarios:
- `en`: host refresh/start-round copy + player submit-guess copy
- `da`: samme flow med dansk copy

Audio-policy delen af samme smoke-spec verificerer:
- host/primary playback path er uændret før player mount
- player mount installerer no-audio guard på secondary device
- guard fjernes igen ved unmount, så primary path fortsat er eneste aktive output

## Recommended verification command
Køres fra `frontend/angular`:

```bash
npm test -- --run src/app/i18n-mvp-flow-smoke.spec.ts src/app/lobby-i18n.spec.ts src/app/features/player/player-shell.component.spec.ts
```

## Why this is the gate
- `i18n-mvp-flow-smoke.spec.ts` giver en lille, samlet smoke/e2e-lignende verifikation af host+player i begge locale-kontekster.
- `lobby-i18n.spec.ts` holder shared locale propagation + contract fallback grøn.
- `player-shell.component.spec.ts` dækker den dybere regressionflade for audio-guard på secondary device.

## Conclusion
Gate’en verificerer nu eksplicit begge locale-runs (`da` + `en`) og bekræfter primary-only audio routing i MVP-flowet.
