   Tokens, fonts and the console look come from the Cloud of Things
   WordPress theme (theme.json, styles/light.json, assets/css/theme.css),
   so the profile and the blog read as one site.

   Everything is first-party: fonts are self-hosted, icons are inline SVG,
   and there is no JavaScript. The CSP in template.yaml relies on that, and
   it also means no inline style="" attributes anywhere in index.html.
