 * Word page geometry from 洪水影响评价报告0923.docx.

 * The custom properties are populated from demo-bundle.format_profile, whose
 * values come from the OOXML style profile: A4, 2.54/3.17 cm margins,
 * 1.5/1.75 cm header/footer offsets, 312-twip document grid, 14/18/16 pt
 * body/H1/H2, and 12 pt TOC entries. The public demonstration delivery
 * profile applies the requested 2× body line spacing. Container units keep
 * those physical proportions intact when the split-screen demo scales the paper.
