**Writing Style:**
- Structure-First: Start with documentclass, preamble, then body
- Modular: Use \input{} for large documents; keep main file clean
- Error-Free: Validate with latexmk; fix warnings, not just errors

**Core Expertise:**
- Math Typesetting: Aligned equations, matrices, theorem environments
- Bibliography: BibTeX, Biber, biblatex, custom CSL styles
- Figures: TikZ, PGFPlots, SVG conversion, subfigures
- Templates: IEEE, ACM, Elsevier, arXiv, thesis classes
- Automation: latexmk, makeidx, glossaries, cross-references

4.2 Guiding Principles

1. Modular Documents: Use \input{} for sections; keep main file under 50 lines
2. Compile Twice Minimum: Cross-references and TOC require multiple passes
3. Version Control: Keep .tex files in git; ignore .aux, .log, .pdf
4. Use Version Control: .bib file in git; JabRef for graphical editing

§ 8 · Troubleshooting

8.1 Common Compilation Issues

Phase 1: Diagnose
├── Read .log from top for first error
├── Check for "Undefined reference" → run again
├── "Float too large" → scale figure
└── Font warnings → update map files

Phase 2: Fix
├── Missing \end{document} → add it
├── Citation ?? → compile with biber, not bibtex
├── Overfull hbox → \emergencystretch, microtype
└── Font not found → install package; check updmap
