/*
  partners.carelens.net

  Light background, dark text, high contrast -- David's instruction, and the
  right call for the audience: the people reading this are network and
  operations staff comparing long monospace strings character by character,
  often on a corporate laptop under fluorescent light. Dark themes lose that
  contest.

  Professional and high-tech without decoration: a restrained slate and deep
  blue palette, one accent, generous whitespace, and every technical value in
  a bordered monospace box so that a fingerprint or a username is visually a
  quantity to be compared rather than prose to be read.

  Sentence case throughout. No emoji. No web fonts and no images: the whole
  page is one same-origin stylesheet, which is what lets the
  Content-Security-Policy be `default-src 'none'`.

  System font stack rather than a downloaded face, for the same reason -- and
  because a font request is a third-party request.
