Three reusable scanners salvaged from the April 2026 math-rendering audit
(branch audit/math-rendering, now retired):
- audit_math_rendering.py - HTML build + LaTeX-leak scanner
- audit_math_pdf.py - PDF build + page-image rendering for spot-checks
- audit_pdf_spot_check.py - regex-driven manifest of fix sites in PDFs
These are useful for any future regression check after a Quarto upgrade
or a large prose edit. Output paths (audit-*-report.{md,json},
audit-pdf-output/) are gitignored so the artifacts stay local.
