/* The Sure Thing.
   Design brief: a compliance notice that happens to be a website. No
   gradients, no glow, no animation that isn't load-bearing. The joke is
   deadpan, so the page has to be deadpan too — the moment it looks zany,
   the transparency stops reading as sincere and starts reading as a bit. */
