/*
  fanout, the page.

  Direction is evervault.com, opened and screenshotted rather than described
  from memory. What transfers is the grammar and not the vocabulary: a row
  carrying a mark, a monospace token, a seller chip and a right-aligned price is
  already a metasearch result.

  One decision here is the repository's argument rather than a colour choice.
  A supplier that ran out of budget is amber and a supplier that failed is red,
  because those are different things and the whole circuit breaker depends on
  not confusing them. Painting both red would be the page contradicting the code.

  Dark is the design; light is the same page with the ground turned over. Both
  are real, because a page that only works at night is half a page.
