I've noticed when using Subeta on mobile that it has a really nice dark mode - I really like how this looks and was wondering if the desktop site has a way to darken the background as well? I know there is custom CSS for user-made ways to do it but they don't do what I'm hoping for. What I'm after is moreso just a way to darken the default site's background that persists between the themes, like what we can do on mobile. Can't seem to find any features relating to this in options or preferences though, so I figured I'd ask here!

Here's a pic of the mobile site's dark mode I'm talking about:

Any help appreciated, cheers!
