/*
  Swingset — the Mining Humans page, turned to the light: paper white, near-black
  words, and the logo's teal. Same layout and the same motion; only the surfaces
  and colours change.

  The logo's teal (#2BB3A3) is too pale to read as text on white, so it is kept
  for the things that are decoration — glows, the rule, switches, the swing
  strip — and a deeper teal from the same family does the words and buttons.
