The docx package's Styles merge spreads our options over its factory
set, so a passed importedStyles array replaced the whole set —
w:docDefaults (default font, size, language) and the Title/Heading1-6
factory slots included. Every document using a table or list style
exported without document defaults; Word fell back to its own. The
style XML is now spliced into styles.xml by a post-pack pass
(applyRawStylesDocx), and the regression test builds with a table
style and asserts w:docDefaults survives.
