For any theming to be applied, you need to tell this module which profiles you're using:

{
  programs.zen-browser = {
    enable = true;

    profiles = {
      my-profile = {
        # bookmarks, extensions, search engines...
      };
      my-friends-profile = {
        # bookmarks, extensions, search engines...
      };
    };
  };

  stylix.targets.zen-browser.profileNames = [ "my-profile" "my-friends-profile" ];
}

This is necessary due to a limitation of the module system: we can either detect the list of profiles, or change their configuration, but we can't do both without infinite recursion.

config.stylix.autoEnable

false
