/**
 * Shared layout constants for the layout / pagination / SVG render modules.
 *
 * These defaults are used when a `SectionProperties` does not specify a
 * page size or margin. Keeping them in a single file avoids drift between
 * `layout.ts`, `layout-full.ts`, and `render-page.ts`.
 *
 * The values match Microsoft Word's defaults for US Letter paper:
 *   - Page size: 8.5 in × 11 in (12240 × 15840 twips)
 *   - Margins:   1 in on all sides (1440 twips)
