Option 1 - new builds are pushed to texlive.latexjs.org (with the rest of the texlive mirror).

• Keeps texlive mirror/releases in lockstep
• How it's already done

• Have to serve extra content from our server
• How to integrate with NPM/GitHub releases

Option 2 - canonical release location is GitHub, with mirror to npm

• Follows the standards!
• Fewer things to serve ourselves

• Have to ensure texlive.latexjs.org and releases are compatible, strong versioning system
• Isn't implemented

Option 2 has to be the way to go longer term...
