 The Redis-backed limiter is required because serverless instances cannot share
 an in-memory counter.
 
+The root `vercel.json` pins the build command to
+`npm run validate:production-env && npm run build`. Missing or invalid production
+configuration therefore fails before compilation instead of creating a
+deployment whose UI works while generation is broken. Preview deployments run
+the same validation. Use Production for the public assessment; if Preview is
+enabled, its `APP_ORIGIN` must match that branch's Preview domain or generation
+requests will be rejected by design.

 After deployment:
 
 1. Visit `/api/health` to confirm the application is reachable. This is a
    liveness endpoint, not a provider or Redis readiness check.
 2. In a private browser window, run a full live-provider build and CRUD flow.
