   uxena - public Articles pages (features/82-articles-and-seo-content.md section 5).

   Served with /articles and /articles/<slug>, which server/articles/render.ts
   renders on the server. Those pages ship no script at all (D-P4).
   The tokens, base, nav, buttons, footer and mobile menu are copied from
   index.html's style block so the pages read as the same site: keep them in
   step with it.
