I'm trying to build a Scribus template for use by people who do not necessarily have some of the fonts that the template prefers.
In CSS one can define a "font-family", such as font-family: "Times New Roman", Times, serif;
or font-family: Arial, Helvetica, sans-serif;
(which isn't really the standard meaning for "font family", but never mind).
I see in the manual (Help:Manual Fontswin32 and Help:Manual Fontsconfig) that it's possible to set font substitution preferences with this dialog box:
But that appears to set user preferences in my instance of Scribus; what I'd like to do is define font substitution preferences for a template instead.
Related question if I have to fall back to Word (which seems even less likely to have a solution at this point): https://superuser.com/questions/1337305/word-font-substitution-in-templates
