Hi Branden,
> Further feedback is welcome.
I see groff's documentation has Roman numerals but roman fonts.
I try to parse roman as something+man. :-)

If the Roman face is for everything else then it seems odd at this point
that bold is needed.

It's only at the end that everything else is probably seen to be ‘digits’.
eqn uses three typefaces to set an equation: italic, Roman, and bold.
Set them to a groff font style with primitives gifont, grfont, and gbfont.
The defaults are I, R, and B in the current font family.
The chartype primitive sets a character's type, see above.
A letter character is set in italics.
A digit character in Roman.
The bold font is used by the bold primitive.
