/* Article pages under /shared/compare/. Deliberately a separate stylesheet
   from the landing page's styles.css: these pages are long-form reading, they
   share none of the hero/shader machinery, and keeping them apart means an
   article can never regress the home page's layout. Tokens are copied from
   styles.css :root so the two stay visually the same product — flat surfaces,
   warm neutrals, one accent, no gradients. */
