  Lido — website styles.

  The colour, radius and spacing values below are the app's own tokens, copied from
  ui/theme/Color.kt and ui/theme/Shape.kt rather than re-picked by eye. If the app's palette
  moves, these move with it; the site and the product should never be two different blues.

  No web fonts: the app draws with the platform's default family, and the site does the same.
  It also means nothing blocks the first paint.
