#    (meaningless in a single doc) and insert page breaks between parts.

# 2) Convert to DOCX with a navigable TOC and code highlighting.

#    which fails strict OOXML validation (Word opens it either way). Self-contained
#    zip rewrite — keeps the valid run-level (<w:rPr>) shd that shades code blocks.
