/*
  One stylesheet, hand-written, colours defined once at the top.

  The values are the app's own — DueThisWeek/designSystem's ramp, copied by hand
  because this repository has no design system and does not need one. The rule
  behind that folder still applies: a hex written twice is a hex that will
  disagree with itself, so they are written once, here.

  No web fonts. The app's pitch is that nothing leaves the parent's phone, and a
  privacy policy served from a page that fetches a font from somebody else is the
  one joke a reviewer will not find funny.
