Issue #207 Artifact — da/en locale switch + audio routing (primary-only)

Scope

Acceptance for [READY][i18n][P19]:

1. Verify one MVP host+player flow in both en and da locale context.
2. Verify controlled fallback to en when a locale key is missing.
3. Verify audio-routing policy is primary-only (client/player has no audio output).

No new feature behavior added — this is verification-only evidence.

Smoke/e2e evidence (Angular shell test run)

Executed from frontend/angular:

npm test -- --reporter=dot src/app/lobby-i18n.spec.ts src/app/features/host/host-shell.component.spec.ts src/app/features/player/player-shell.component.spec.ts

Evidence covered by the run:

• lobby-i18n.spec.ts
  • subscriber locale switch updates (en -> da -> en)
  • controlled fallback where da key is removed during test and en copy is returned
  • clientHasNoAudioOutput === true (primary-only audio routing)
• host-shell.component.spec.ts
  • host actions and route sync in SPA (no reload)
• player-shell.component.spec.ts
  • player session refresh/sync path and retry behavior

Policy evidence

• Shared catalog capability: shared/i18n/lobby.json
  • frontend.capabilities.client_has_no_audio_output = true
• Angular host/player shells bind this capability:
  • HostShellComponent.clientHasNoAudioOutput
  • PlayerShellComponent.clientHasNoAudioOutput

Conclusion: locale switching works in da/en, fallback resolves to en when locale key is intentionally missing, and client audio remains disabled by policy (primary-only).
