% LaTeX preamble for "make latexdocs" or "make pdfdocs" including:
%   - TOC width settings
%   - Setting of tabulary (\tymin)
%   - Headheight setting for fancyhdr
%   - Fontfamily settings for CJK (Chinese, Japanese, and Korean) translations
%
% Note on the suffix of .sty:
%   This is not implemented as a LaTeX style file, but as a file containing
%   plain LaTeX code to be included into preamble.
%   ".sty" is chosen because ".tex" would cause the build scripts to confuse
%   this file with a LaTeX main file.

% Custom width parameters for TOC
%  - Redefine low-level commands defined in report.cls.
%  - Indent of 2 chars is preserved for ease of comparison.
% Summary of changes from default params:
%   Width of page number (\@pnumwidth): 1.55em -> 2.7em
%   Width of chapter number:            1.5em  -> 2.4em
%   Indent of section number:           1.5em  -> 2.4em
%   Width of section number:            2.6em  -> 3.2em
%   Indent of subsection number:        4.1em  -> 5.6em
%   Width of subsection number:         3.5em  -> 4.3em
%
% These params can have 4 digit page counts, 3 digit chapter counts,
% section counts of 4 digits + 1 period (e.g., 18.10), and subsection counts
% of 5 digits + 2 periods (e.g., 18.7.13).

            instructions from

            Having optional non-variable ``Noto Serif CJK'' font families will
