This repo serves the built course site via GitHub Pages, deployed from the
gh-pages branch (published there by the private src repo on every content
change).
This main branch holds nothing but .github/workflows/pages.yml — the
deploy workflow that publishes gh-pages's content. It lives here,
deliberately not on gh-pages, because that branch is fully replaced by
every deploy.
