/*
  The pairing page. Phone first — it is read on the phone of someone standing
  in front of a TV — and dark, with the values of docs/design/tokens.css so the
  page and the app are recognisably one product. Only the tokens this page uses
  are copied; the px values there are the 1920 TV canvas, and on a phone they
  are read as CSS px directly, which is the dp the brief names.

  Nothing is loaded from anywhere: no font, no image, no script but our own.
  Nothing animates, and there is no spinner and no progress element (ADR-0008
  carrying rule B) — while a delivery is in flight the button is disabled and
  says so.
