What wrong with inlining base64 in regular .html if you want it all in one file?

Plus zipping that one file is you insist on a smaller file size

Same zip also helps serving .hmml from cdns smaller (gzip/brotli)

Even then base64 is worse in size though

Also I wouldn't prefer serving a zip and load and render it within my web app (extra overheads).
