This method is humorously different than what I had imagined :)
It does work.  Though there seems to be a "gotcha" that would be
problematic if I can't find a way to work around it....

- When I import the .ps file through the "Import > Get vector file" option,
the code is placed on a large white canvas, the code takes up a small
portion of the canvas, and there doesn't seem to be any way to crop it.
- When I import it as an image frame the resolution is horrible, so I go
into the filename.html and set large fontsize, reopen that in firefox, and
re-print to the post script file.  By the time I've enlarged the font
enough to get a good resolution in Scribus, half of the code is
clipped/cropped out of the image.  And playing with this some more, the
background color that is specified in the .html file does not seem to get
preserved when firefox goes to print it and the font colors get altered
then as well.

I would add that I tried importing the HTML to Scribus into a text

Yeah I see the colors are lost.  Line breaks also seem to be lost.

This is a very different angle than what I anticipated.  I wonder if it
would be better to go forward in this direction trying to resolve the
issues I'm seeing or if it would be better to try something more along the
lines of what I did previously with LaTex?  Or maybe there are still other
methods?  The LaTex method seems like it might be most appropriate, but I'm
a bit ignorant here so that might be a poor assessment.
