% These "jumps" are measured baseline-to-baseline. So, \SetHeadJump{1} means
%   that the baseline of the header is 1 baselineskip above the baseline of
%   the first line of textblock. In other words, on-grid. Value 2 would be
%   equivalent to double-spaced vertically. A value of 1.5 is default, based
%   on observations of actual novels.

%% DEFINITION OF PARENT AND OTHER FONTS
%% --------------------------------------------------------------------------
%% Prior to v. 1.1, parentfont was known as masterfont. Backwards compatible.
%
% These are the LaTeX defaults, which should already be built-in by now.
% But just in case they are undefined, here they are set to LaTeX defaults:
\providecommand\rmdefault{lmr}
\providecommand\sfdefault{lmss}
\providecommand\ttdefault{lmtt}
% The `no-math' option prevents fontspec from tracking certain font changes.
% This is probably necessary, since novel does some of its own font tracking:
\RequirePackage[no-math]{fontspec} % For LuaLaTeX. NOT package `fontenc'.
\defaultfontfeatures{} % reset
\defaultfontfeatures{SmallCapsFeatures={Renderer=Basic},Ligatures=TeX,}
% Main and sans fonts: kerning, ligatures, and OldStyle numbers if available:
\defaultfontfeatures[\rmfamily,\sffamily]{Kerning=On,Numbers=OldStyle,Ligatures=Common}
% Package `unicode-math' uses Latin Modern Math as default math font:
\RequirePackage{unicode-math}
%

%   arguments to appear in either order. We wish to store the fontnames
%   and arguments, but need Expl syntax to tell which is which.

%% \CreateFontFeature{substitutions}{feature code}
% Problem: Font has one or more alternate glyphs that you would like to use,
%   but they are not listed in a feature set for the font.
% Solution: Create your own feature set, with \CreateFontFeature. The created
%   feature may then be used like a real feature, in any font definition.
% The substitutions are a comma-separated list, char=char.alt and so forth.
% For example, the following substitutions are syntactically OK:
%   emdash=emdah.alt, one=one.rev, ntilde=ntilde.03
% If a substitution is not available in a particular font, it is ignored.
% You have to look at the font in a font editor, to know what is available.
% It is possible to make silly substitutions, such as a=b, five=three without
%   throwing an error, unless your code causes a cycle.
% The most useful application of this command is to reach alternate emdash,
%   and alternate oldstyle one. Not every font has these.
% The feature code is a 4-character pseudo- Open Type code, otherwise unused.
% For example, the feature code might be myfs (my fake substitution)
%   but it cannot be a pre-defined code such as lnum or smcp. It may be
%   a style set such as ss03 if you are sure that the font in question
%   do not already have ss03 (but this is taking a chance).
% Once defined, you may use it like this (for example):
%   \SetParentFont[RawFeature=+myfs]{fontname}
%   \NewFontFamily\myfake[RawFeature=+myfs]{fontname}
%   In the document body: {\addfontfeature{myfs} text}
