+## Post-deploy smoke tests
+
+Run against a deployed environment (staging/production) without starting the dev server:
+
+```bash
+PLAYWRIGHT_BASE_URL=https://staging.veza.com npx playwright test --config=playwright.config.smoke.ts
+```
+
+Or with `VITE_FRONTEND_URL`:
+
+```bash
+VITE_FRONTEND_URL=https://app.veza.com npx playwright test --config=playwright.config.smoke.ts
+```
+
+In CI (cd.yml), the smoke job runs after deploy when `STAGING_URL` (secret or variable) is configured.
