+# docusaurus-fmt-check belongs here, not only in CI. A change merged from a
+# security advisory's private fork runs no Actions at all, so this recipe is
+# the only pre-merge gate those fixes get. Three of them left five pages
+# unformatted and broke Docusaurus Lint on main in September 2026.

+# md-fmt-check is deliberately absent: it needs uv, which the Go workflow does
+# not install, and Markdown Lint already runs it with uv available.
