Noto Sans Math woff2
Temml supports only ttf in Noto Sans Math, but the following package provides woff2 version:
https://www.npmjs.com/package/@fontsource/noto-sans-math
A new Temml-*.css variant is wanted.
.ttf version is nearly 1MB and too fat but .woff2 in the package is only about 220kB.
In the first place, there should be a Temml-Custom.css, where no font-family is not specified.
Noto Sans Math … woff2 version
I tried the woff2 version from https://fonts.google.com/noto/specimen/Noto+Sans+Math. The math rendering was dreadful. None of the delimiters stretched. None of the arrows stretched. So I reverted to the ttf version.
I do not expect any web site to ship a 1MB font file. I have included Noto Sans so that Windows users and MacOS users can see what system font math will look like if and when Google makes Noto San Math a part of their operating systems.
there should be a Temml-Custom.css
Temml CSS files are not complex. Feel free to take one, rename it, and customize it to your needs.

I think we can get only a reduced .ttf file (574kB).
I tried converting the original .ttf (992kB) and .otf (487kB) to .woff2 and got 337kB and 293kB. Noto Sans is the only major sans-serif math font and matches the surrounding text (mainly sans-serif).

It's best to copy the bundled style sheet in the latest Temml to the build directory by using a copy plugin of the bundler (e.g. copy-webpack-plugin, CopyRspackPlugin, or vite-plugin-static-copy). I don't want to manage it in Git by myself.

By this plugin Docusaurus users will have only to manage Temml version in package.json / lock file.
