Usage:
  scripts/github-workflows/deploy-vercel-app.sh \
    --label "Docs app" \
    --project-id PROJECT_ID \
    --public-urls "https://example.com https://www.example.com"

Deploys one Vercel project to production from the current checkout:

1. configures Vercel Authentication to protect preview deployments only
2. runs vercel pull/build/deploy --prod with the project root taken from the
   Vercel project settings
3. verifies each public production URL responds with HTTP 2xx/3xx
4. appends a deployment summary to GITHUB_STEP_SUMMARY when set

Requires VERCEL_TOKEN and VERCEL_ORG_ID in the environment and the vercel CLI
on PATH. Run from a production-layout checkout (a main publish commit).
