/* FakeYeast paper companion, BYO static-site fixture (demo lab). Hand written CSS
   so the bundle reads like a real lab built it, not a framework export. The theme
   leans into the science, fakeGFP fluoresces green, so the lab's signature color
   is an emerald that glows against a deep ink. No external fonts or assets, the
   whole bundle is self contained and served from a sandboxed origin. */
