Thanks, that helps a lot; d'oh.

I see the EPS file appearing in the output; the graphics aren't there,
but I assume this is because there is faulty scaling/translation.

Unfortunately, there is a more serious problem. None of the drawing
commands issued after the EPS embedding make it to the PS output.

See the attachments on https://gitlab.com/hanwenn/lilypond/-/issues/1

As you can see, the one with embedding enabled simply ends with

cairo_eps_end
Q
Q Q
showpage
%%Trailer
%%EOF

in the output, it's missing a notehead and the tagline at the bottom.
