   Tokens are the same ones the product uses (bintweb src/index.css), so the
   portal is itself an example of the identity it hands out. Space Grotesk is
   self-hosted from fonts/ rather than fetched from a CDN — the portal has to
   render correctly on a machine that cannot reach the internet, which is the
   same machine a designer is often on.
