/*
  Recipes' Cast screen. Colours, type, spacing and corners come from
  design/tokens.json (copied here by hand: keep them in step). Light and
  dark follow the phone: the phone sends its theme and the page sets
  data-theme on <html>; before it does, the device's own preference.

  Everything is sized in rem, and 1rem is a thirtieth of the screen's
  height (or less on a screen narrower than 16:9), so the layout is the
  same on a 1080p TV and a 1024×600 Nest Hub.
