Automated Zero-Downtime Deployment Pipelines with GitHub Actions & Vercel

Shipping with confidence requires robust automated validation before code reaches production. Every pull request must undergo strict linting, type-checking, and preview deployment verification.

GitHub Actions CI Workflow (.github/workflows/ci.yml)
