# ISSUE-257 Artifact — shared i18n keyspace + frontend loader (Angular-first)

Issue: **#257** (`[MVP][READY] #175-B: Shared i18n keyspace + frontend loader (da/en, Angular-first)`)

## Acceptance mapping

### 1) Delt key-strategi dokumenteret (frontend/backend)
- Shared contract source: `shared/i18n/lobby.json`
- Architecture doc: `docs/I18N_ARCHITECTURE.md`
- Key-map/contract doc: `docs/ISSUE-226-SHARED-KEYMAP-LOCALE-CONTRACT.md`

### 2) Frontend loader kan indlæse da+en med samme keyspace
- Shared loader: `frontend/shared/i18n/lobby-loader.ts`
- Angular-first consumer path:
  - `frontend/src/spa/lobby-i18n.ts`
  - Angular shell/tests continue to consume same shared catalog through shared loader contract.

### 3) Minimal check for key-paritet da/en
- Guard test: `frontend/tests/lobby-loader.parity.test.ts`
- Contract test: `frontend/tests/lobby-i18n.contract.test.ts`

### 4) Ingen API-kontraktbrud
- Frontend API contract smoke:
  - `frontend/angular/src/app/api-contract-smoke.spec.ts`
  - `frontend/tests/angular-api-client.test.ts`

## Verification run (this lane)

```bash
cd frontend
npm test -- --run tests/lobby-loader.parity.test.ts tests/lobby-i18n.contract.test.ts tests/angular-api-client.test.ts

cd ../frontend/angular
npm test -- --run src/app/api-contract-smoke.spec.ts
```

Result: PASS (all selected suites green).
