The generated latex/main.tex includes a table of contents (tocdepth=2) for readability.
Language default: the scaffold uses article (English-looking front matter). If the draft contains CJK characters, it switches to ctexart so the PDF renders correctly.
Conversion rules (high level):
Headings ##/###/#### → \section/\subsection/\subsubsection (strips leading numeric prefixes like 1.2).
Headings starting with Appendix / 附录 trigger \appendix once, then render as appendix sections.
Bold caption lines like **Table 1. ...** / **Appendix Table A1. ...** immediately before a Markdown table become a LaTeX table float with \caption{...} and a stable \label{tab:...}.
## Abstract → abstract environment.
[@Key] or [@Key1; @Key2] → \citep{Key} / \citep{Key1,Key2}.
