/*
  Isogonic, marketing and legal site.

  Same art direction as the app: near black, magenta brand, generous
  measure. Deliberately one small stylesheet and no framework, because the
  whole point of these pages is that an App Store reviewer, or a pilot on a
  bad airfield connection, can open them instantly.
