This would be fairly easy to implement on this backend — I could submit a pull request. The only complication is that it requires backend rendering of the <head> element of the page. If you tell me a preferred backend HTML preprocessing library to use for this backend (I've worked with a lot of them & don't have a strong preference), I'd be happy to get right on implementing this :)
Here's an example of what I'm talking about:
StyleBase (right now)

Stylish Userstyles.org

UserStyles.world
