   The bones of this are the Nubar site's stylesheet, turned inside out for a
   dark canvas. Same idea: a small set of tokens at the top, and every screen
   built from them. Change a value here and the whole site follows.

   On black, shadows do almost nothing, so the work of separating one surface
   from another is done by hairlines and a slightly lifted card colour.
