This GTK3 theme is part of the Phocus theme collection.
Libadwaita applications can't be themed through a GTK4 theme. The amount of non-libadwaita GTK4 apps is so little, that it is not worth adding a phocus GTK4 theme.
You can manually overwrite the libadwaita colors to somewhat get a phocus feeling. Feel free to copy this example from my dotfiles ~/.config/gtk-4.0/gtk.css. This won't get you the phocus look you are used to, but it is the best we can do.
May proper GTK4 theming rest in piece 🪦

I am actively working on phocus and other cool projects on the Desktop Makers Discord. It aims to be a community for communities of Linux desktop related projects. If you are looking to collaborate with or want to contribute to great projects, this might be the right place for you.
