Base-URL site issue and feature request

Summary

The current docs.rust-lang.org has two things that I think could be changed:

1. [Issue] The theme-selection applies to std but not to the main url (that above) which is always bright white. (I'm aware I could just use stylus and write own style, but that's not the point.)
2. [Feature Request] Just as we can change the theme I'd like to have a cookie that defaults to one of stable / beta / nightly and it redirects to such url when possible.

Having this landing page respect the rustdoc theme selection is probably out of scope, since it is not actually part of rustdoc.

however, it should be fairly easy to just make rust.css respect the prefers-color-scheme media query.

I disagree, it should have the same style, which is what most would expect.

But the landing page also links to mdbook stuff, and those have their own theme selector.

Yeah, ideally those could all be kept in sync, but that would require substantial effort, while simply adding dark theme support to the landing page would be much simpler and would still be a huge improvement.
