/*
  Cave Escape — the public site.

  The palette is docs/index.html's, unchanged, and the display face is the game's own Grenze, so
  the site, the store capsules and the game all read as one thing. Committed to a single dark
  theme for the reason every page in docs/ gives: everything pictured here is a pitch-black cave
  lit by one torch, and a light ground would misrepresent all of it.

  External rather than an inline <style>, which is the one place this diverges from the docs/
  house style. Those pages inline theirs because they must open from file:// with no server. This
  one is served, so keeping 'unsafe-inline' out of style-src in public/_headers costs nothing.
