   Site chrome — header and footer.
   ─────────────────────────────────────────────────────────────────────────
   The markup for these comes from one module (routes/chrome.ts), so their
   styles come from one file. They used to be split across blog.css and
   pages.css, and because the blog only loaded blog.css, every article showed
   an unstyled mega-menu and a footer collapsed into a bullet list.

   Loaded last by every layout, so anything it declares wins.
