   Pages.css holds the named replacements for the inline grid/padding
   declarations that live on <section> / <div> wrappers in the static
   reference. Component-level classes (cards, pills, sidebars, TOC, nav,
   breadcrumb, footer, etc.) live in components.css; element defaults
   live in base.css; long-form typography in prose.css.

   Every value references a token from tokens.css. No hardcoded hex,
