For arXiv papers, extract figures directly from TeX source instead of
heuristic PDF region cropping. Parses \begin{figure} environments,
resolves \includegraphics paths from e-print tars, and outputs the
same manifest format for drop-in compatibility.
Benefits over PDF extraction:
- Original image files (vector PDF, high-res PNG) instead of screenshots
- Structured \caption{} text without hyphenation artifacts or truncation
- Subfigure splitting (composite figures become individually referenceable)
- Appendix figures captured via recursive \input{} expansion
Falls back to PDF extraction for non-arXiv sources.

Summary
scripts/paper_extract_figures_tex.py— extracts figures from arXiv TeX source instead of heuristic PDF region croppingWhy
PDF-based figure extraction uses heuristics to guess figure boundaries, which causes:
TeX source gives us structured
