  Drop — visual system.

  Deliberately single-theme. This is an arcade cabinet, not a document: the
  orb ladder is a hue sweep that only reads against a dark ground, and a light
  variant would flatten the one piece of information the palette carries.
  Every colour is therefore painted explicitly rather than inherited, so the
  page holds up wherever it is embedded.
