   ABOUT — the hero → about transition.

   The section rises into the bottom of the hero as a narrow arch (a
   doorway), and widens as you scroll until it is the section's whole
   surface (js/about.js writes --ax, the side inset, and --ar, the top
   radius). Glass objects float on it, over soft shapes they blur.
