name: Docs Deploy (GitHub Pages)

# Static-export deploy of docs/ to GitHub Pages. Pages must be enabled in repo
# settings (Source: GitHub Actions) and the docs.sanaei.dev custom domain
# attached to this repository. The site URL defaults to the production domain in
# docs/lib/shared.ts, so NEXT_PUBLIC_SITE_URL is optional.
