   The background light simulation — sections 3 and the sunrise/sunset
   keyframes — is adapted, with thanks, from "sunlit" by Jacky Zhao:
   https://github.com/jackyzha0/sunlit
   assets/img/leaves.png comes from that project as well.

   Everything above it is a reading-first type system: the room is
   atmosphere, the text is the point.
