/* NEITHER END IS TAKEN TO ITS EXTREME. The app's own dark surface is #1A1C1E,
   which is right on a phone held at night and reads as a black page in a browser
   window - and it was darker than the phone screenshots lying on it, so every
   image glowed like a light box. The light end started at #FBFCFE, near enough
   to paper that the cards on it had nothing to lift off. So the page sits a step
   in from both: a soft grey-blue in light, a lifted charcoal in dark, with the
   cards and the code blocks moving the other way in each. */
