% \paragraph{Booleans}
% \subparagraph{firsttime} As \cs{keys_set:nn} is run multiple times, some of its
% information storing only occurs once while we decide if the font family
% has been defined or not. When the later processing is occuring per-shape
% this no longer needs to happen; this is indicated by the `firsttime'
% conditional.
