% TOC customization
% The tufte-latex package relies on titletoc for TOC formatting.
%
% But the spacing between the section number and the section name is too small
% if the section name is too big.
%
% Example: "10.10Section name" instead of "10.10 Section name"
%
% Therefore we need to reset \titlecontents for section.
%
% The original code is full of "FIXMEs", so maybe this should be filled
% upstream as a bug, along with a Minimum Working Example (MVE).
