I see!  Thank you.  I should have realized that.

I wonder where they came from?  If there are other fonts out there with
compatible metrics, maybe they could be dropped in.

For the typewriter font the body of the paper is set in, that should be
pretty easy (its “m” and “i” are evidently the same width, and similarly
“M” and “-”, so it’s almost certainly fixed-pitch, even though the word
spaces and letter spaces vary for justification).  However, the serif
roman font used for the title and the letterhead, if that’s the term,
evidently has variable pitch.  If we’re lucky, it’s just the Hershey
version of Times New Roman, a question which seems likely to be obvious
to people who know fonts better than I do.

Is the BDF conversion lossy?  Glancing at the Python, it doesn’t appear
to be thresholding grayscale or anything like that.

Reverse-engineering outline data from raster data with something like
potrace (or, since it’s 02026, running gradient descent on a
differentiable polygon filling program) might be an interesting
challenge, but I don’t think I’m up to it this week.

Hilarious!
