/* ==========================================================================
   Onyx site chrome — shared header + footer
   --------------------------------------------------------------------------
   The header and footer are identical across every landing page, but the
   pages themselves run on three different stylesheets (legal-doc.css,
   legal-pages.css, styles.css). This file carries only the chrome, so a page
   can adopt it without inheriting a foreign page layout.

   The eight legal pages already get these rules from legal-doc.css and do not
   load this file; the declarations here are kept byte-identical to that copy
   so the two never drift apart visually.

   Custom properties are declared on the chrome roots rather than :root, so a
   host page's own token names are left untouched.
