/*
  Design rules for this app (older eyes and young thumbs):
  - Phone first. One column. Big type (20px base), big buttons (56px), plain words.
  - Contrast of 7:1 or better for text. Color is never the only signal (words and symbols too).
  - Every control has a visible label and a clear focus ring.
  - City colors are variables below so a city can restyle the whole app in one place.
