"Emergency stop" in `_global_settings.tex`

[arnold117]

In TexLive 2025 ran on Windows, I encountered "Emergency stop" in _global_settings.tex.

This is raised due to input before documentclass.

I suggest move the following snips to main.tex before \input{_global_settings.tex}.

\ifdefined\DoubleSided
  \documentclass[twoside,openright,a4paper]{nusthesis}
\else
  \documentclass[a4paper]{nusthesis}
\fi
