/* DespatchOS guides — TASK-941 / DEC-349.
   Source: site/assets/guides.css → holding-page/assets/guides.css (scripts/build-guides.js).
   The guide body is set in the brand face (Instrument Sans + IBM Plex Mono, DEC-282);
   the site header and footer stay on site.css as they are. Tokens are BRAND.md only.
   The font faces are declared in site.css (TASK-942), which every web guide page loads
   first; the PDF print path inlines the faces itself (build-guides.js), so the
   --g-sans / --g-mono stacks stay literal here rather than pointing at site.css. */
