/* The home page, fourth test copy (/home-v4.html, 21.10): a full redesign in
   the manner of YC-backed product sites. White, one sans family set tight, a
   soft glow behind a product frame, bento tiles, dark bands for developers
   and the final call. The product's own screens (the 3D plate, the shop page)
   keep their look; their tokens are set here because this page loads nothing
   of picker.html. */
