/* ── Site-wide header and footer ──────────────────────────────────────────
   Injected into every static page by lib/chrome.js, and mirrored by
   src/components/Chrome.jsx for the React homepage.

   Every selector is namespaced .oc-ch* on purpose. The pages this lands in
   were each written standalone with their own CSS conventions (.ed, .solid-bg,
   editorial.css, system.css…), so the chrome has to be unable to collide with
   any of them, in either direction.
