   Loaded alongside site.css, never alone. It supplies the article column,
   prose typography and the editorial components (callouts, pull quotes,
   flow diagrams, comparison tables); nav, footer, brand mark, buttons and
   every colour token come from site.css so these pages read as part of the
   same site rather than a bolted-on blog.
