build.mjs uploads generated files to two S3 "folders": one named for the branch and one for the commit hash. The latter is never referenced or documented.
The commit hash is also passed as a query parameter when rendering the HTML document. It looks like this is never used.
Should these features be removed? Documented? Or perhaps extended e.g. it would be useful if the rendered document gave the commit hash from which it was generated and a permalink to where this version can be accessed.
