Safe DOCX posture
w:styles style-definitions part emission
w:styles is the root of the style-definitions part. From-scratch
generation always emits word/styles.xml — document defaults, a default
Normal paragraph style, and every declared named style — wired through a
content-type override and a styles relationship from the main document
part. The emitter lives at
packages/docx-core/src/generation/emit/styles-part.ts.
