name: deploy-pages

# Builds the Astro site (site/) and deploys it to GitHub Pages. TechAPI owns its
# own homepage, so it deploys itself (Pages is per-repo). No backend here — the
# static JSON dump the site consumes is produced by TechEngine and committed
# under site/public/v1 (served at <base>/v1/...).
# Enable once: Settings → Pages → Source = GitHub Actions.
