Export themes:
- Six presets in the export dialog (basic + advanced modes) for PDF/DOCX:
Default, Modern, Classic, Sepia, Minimal, Elegant
- PDF: LaTeX header (xcolor/titlesec) recolors headings, adds section
rules and colored links — core-TeX packages only, hex-literal only
(no injection surface)
- DOCX: styles.xml surgery recolors Heading1-6/Title/Subtitle/Hyperlink
and swaps heading/body fonts; verified end-to-end against a real
pandoc-produced docx
- Themes ride along in export presets (unknown ids fall back to Default)
Windows CI fixes:
- pdfjs standardFontDataUrl now a file:// URL (backslash paths failed
pdfjs's trailing-slash validation, breaking extractText/extractImages)
- sharp temp cleanup EPERM retries; path-separator assertions; pdfjs
test timeouts raised; batch suite testTimeout 30s
648/648 tests green; 4.7.1 linux+win artifacts rebuilt.
