I see, but since Guix builds G-Golf from git rather than a tarball,
examples/gtk-4/layout-manager.scm had worked already with rc6.

Tarballs contain bundled M4 files and other build-aux files.  Guix
rather uses its own packaged version of these, avoiding something like
the xz vulnerability’s code injection.  Still it is good that you fixed
the tarball.

This helped.  When manually run, missing gtk-init import and use was the
issue; thank you!  Funny enough, when auto-started, gtk-init is run by
GtkApplication or perhaps by some library constructor, but I also had
forgotten to actually call add-css-class.  Still I added gtk-init, so I
can manually run my launcher as well.

In case others use it as reference, the fixed version is attached.
