/* Shared "Field Manual" design system for the three audience-specific
   guides (FieldOpsGuide, AdminGuide, ContestGuide) and the /Help landing
   page. Originally authored as a one-off inline <style> block in the old
   standalone wwwroot/UserGuide.html; extracted here so all three guides
   (plus any guide added later) share one consistent look instead of each
   carrying its own copy. See project_documentation_guides memory for the
   initiative this belongs to. */
