%%
%% This file is loaded \AtEndPreamble.
%%
%% Most TeX installations will use Latin Modern or Computer Modern
%%   as default fonts. These are unsuitable for commercial fiction.
%% But `novel' class uses Libertinus as defaults.
%% Change them using \SetParentFont and other fontspec commands, in Preamble.
% Libertinus Serif has Regular, Italic, Bold, Bold Italic.
% Here, Semibold over-rides Bold.
%
%% Now to activate the font definitions:
%
\defaultfontfeatures{} % reset
%
% The mono font:
\defaultfontfeatures[\ttfamily]{% monofont has no kerning or common ligatures
  SmallCapsFeatures={Renderer=Basic},Ligatures=TeX,%
}%
\ifthenelse{\equal{\ttdefault}{lmtt}\OR\equal{\ttdefault}{cmtt}}{% over-ride:
  \IfFontExistsTF{Libertinus Mono}{

      BoldItalicFont={},%
    ]{Libertinus Mono}
  }{
    \IfFontExistsTF{Linux Libertine Mono O}{
      \setmonofont{Linux Libertine Mono O}
    }{
      \setmonofont{Latin Modern Mono}% Eeek! Only because you have it!

  }
}{} % User \setmonofont, so leave alone.
%%
\defaultfontfeatures{} % reset
% Main and sans fonts: kerning, ligatures, and OldStyle numbers if available:
\defaultfontfeatures[\rmfamily,\sffamily]{%

% The sans font:

% At this point, if \rmdefault is something other than lmr, it means
%   that the user attempted to set the main font using ordinary TeX commands,
%   or via fontspec's \setmainfont. But those are ineffective in this class,
%   because without \SetParentFont the prior command will be over-written.
