/*
  demo.css

  The look of the demo player. We're going for elegant and calm, more like
  a nice magazine than a tech dashboard: a serif font for headlines and the
  big score, thin gold lines, and lots of room to breathe.

  How it fits in: demo.html loads this file. Our colors are set once in :root
  below. Gold is the brand, black is the base, and red only ever means danger
  (a likely scam, an alert, Grandma's warning).

  Phones first: the main styles are for small screens, and bigger screens
  get the side by side layout at the bottom.
