   Fresh, calm, high-contrast. Indigo carries the brand, teal carries "good
   news", and everything else is a warm-cool neutral so the colour that does
   appear actually means something.

   Every colour is a token on :root and re-declared under [data-theme] so the
   whole app flips to dark without a single component knowing about it.
