There doesn’t seem to be any specific class currently.

I found [this](https://meta.discourse.org/t/add-currentthemeid-into-body-css-classes/161380/2) but it doesn’t work since the theme’s ID is the same for the dark and light mode (which is defined the color scheme, I guess).

I suppose a short script could help? And, maybe add this to Discourse’s core?
