Safe DOCX posture
w:pgSz page size emission
w:pgSz carries the page width/height in twentieths of a point and an
optional orientation. The generation section emitter
(packages/docx-core/src/generation/emit/section.ts) emits explicit
w:w/w:h for every section (defaulting to US Letter) and sets
w:orient="landscape" with swapped dimensions when the spec requests
landscape, so readers never fall back to printer-driver defaults.
