slothitude ee3a4ce5c5 Replace fpdf2/python-docx export stack with pandoc + Playwright 
PDF export now uses Playwright's Chromium for proper CSS rendering —
nested lists, tables, links, inline formatting all handled natively.
DOCX export now uses pandoc subprocess instead of regex HTML parser.
Removed python-docx and fpdf2 dependencies.
