   ---------------------------------------------------------------------------
   Type does the work here. There is one accent colour per project and almost no
   chrome otherwise: no shadows on text, no borders that a gap could do instead,
   no gradient that is not lighting something. Motion is a single gesture --
   16px up and into opacity -- reused everywhere so the page feels like one
   object rather than a stack of effects.
