Two Theme builder live websites

[Basyras]

Describe the bug

From this blog post: https://material.io/blog/material-theme-builder I got this link to theme builder website: https://m3.material.io/theme-builder

Seems like the website is not the most updated one e.g. not using new elevation system described here:
https://material.io/blog/tone-based-surface-color-m3

Later I found this issue: #214
where @margeeta provided link to another website: https://material-foundation.github.io/material-theme-builder
that appears to be more "updated" but as already stated here #244 it is missing tokens.css and typography-module.css when exporting to web.

My questions:

1. Is the first link (https://m3.material.io/theme-builder) sort of production version that is not (yet) updated and the second link (https://material-foundation.github.io/material-theme-builder) is some staging one or we are having two websites running in parallel.
2. Is there a reason (or bug) in second website that is missing tokens.css and typography-module.css?

To Reproduce

1. Visit https://m3.material.io/theme-builder website
2. Export to web
3. observe missing new surfaces colors
4. Visit https://material-foundation.github.io/material-theme-builder website
5. Export to web
6. observe surface colors added but missing tokens.css and typography-module.css

Expected behavior
Only one website existing with both surfaces colors and tokens.css and typography-module.css

Man, I thought I was loosing my mind.
I somehow ended on the material-foundation's theme builder and I downloaded a theme as a JSON, had to close my browser, and when I searched for it again, I landed on the theme builder on m3.material.io.
I noticed weird things happening, like demo buttons not being clickable, and that the export didn't have a JSON export.
Took me a while to retrace my steps and realize they're 2 different websites.
Confusing.

Also, what's with the high-contrast and medium-contrast schemes?
I can't find any way to generate those using the material color utilities...

The Github page version has been a staging version of MTB web, we decided to open it up to give user's earlier access to updates.
