   TRACE CHROME — the site header, footer and Request-access modal.

   One copy for every page. Requires /assets/trace-base.css for its
   tokens; load this second, then the page's own sheet.

   Companion markup, inlined at build time by build/htmlIncludes.ts:
     partials/nav.html
     partials/footer.html
     partials/access-modal.html
   Companion behaviour: /assets/trace-chrome.js
