/* Print stylesheet (Implementation Unit U7). Linked with media="print", so these rules
 * apply only when the reader uses "Download PDF" (window.print()) or the browser print
 * dialog. Brand fonts come from colors_and_type.css's local @font-face (linked for all
 * media) — no Google Fonts dependency in the printed output (R8). Token-only; no raw hex.
 *
 * Page numbers use paged-media margin boxes where the engine supports them (Prince,
 * Paged.js); Chromium ignores margin-box content, so page numbers are best-effort — see
 * the plan's Open Questions. */
