Closes: #1840

I've separated this pull request into two commits to make comparing the original font sizes with the new font sizes easier. I did this since I'm not sure if those font sizes are completely correct. After that's done, I'll squash everything.

Could you add a testbed for this module, as they are immensely valuable?

Just did. Based on what I'm seeing, I'll have to make some extra changes to the theme before it could be considered acceptable.

@trueNAHO So far, this is what I have:

Sherlock also has an 'Additional actions' section in the context bar that I, for the life of me, cannot figure out how to style:

I'd also like to style the window borders, but again --- I can't figure out how to do this. Maybe it's just that I've never styled a gtk app before. Any help would be appreciated.

Considering Sherlock seems to have its own configuration, it is possible it does not yet support this:

    xdg.configFile = {
      [...]
      "sherlock/main.css" = mkIf (cfg.style != "") {
        text = cfg.style;
      };

-- github:nix-community/home-manager, /modules/programs/sherlock.nix:148

In that case, consider investigating upstream.

Otherwise, it might be possible the more aggressive Adwaita overlay from #2107 might be necessary. Although, that seems less likely to be the root problem.
