Deployment

Staging

Staging automatically deploys on push to develop branch.

git push origin develop
# → Triggers GitHub Actions workflow
# → Runs tests, builds, deploys to staging

Production

Production deploys on push to main branch (requires manual approval).

git checkout main
git merge develop
git push origin main
# → Triggers GitHub Actions workflow
# → Requires reviewer approval
# → Runs tests, builds, deploys to production

See DEPLOYMENT_GUIDE.md for detailed instructions.
