-      #       script that generates the index.html automatically. Perhaps
-      #       we could even generate this to automatically download
-      #       web-tree-sitter and maybe even generate playground.js from
-      #       the upstream playground.

-      #       Also, we would likely want to replace peaceiris/actions-gh-pages

-      #       preinstalled in the runner.
