/* The style of the two sites. The colours are `palette.dart`'s, light and
   dark, and they switch palette with the phone like the game: no switch,
   because the page is looked at once and not lived in. `--border` is the
   floor, `--goal` the boulder on its goal. `test/sites_test.dart` holds every
   token to the palette: copied by hand, four had drifted, and the faint
   text and the dark filled labels had fallen under 4.5:1. */
