/*
  Sim Game Studio: the one stylesheet for the whole site (the homepage, the game pages, the
  legal documents, the 404). Dark navy, off-white text, one lime accent used sparingly, blocky
  2px borders, square corners. A system font stack and no url() of any kind: the site loads
  nothing from anyone, and tests/site.test.ts fails if that changes.

  Colours: navy and lime are Pocket Goal's own (the icon's night sky and the keeper's kit).
  Every text pair below is at least 9:1 on its background; --line is 3:1 on --bg, as a border
  that marks something you can press has to be.
