   1Meeting — design tokens and primitives.

   Dark by default and deliberately so: a meeting window is looked at for hours,
   usually beside a bright document, and it should recede rather than compete. The
   accent is used sparingly — on exactly one primary action per screen — so that when
   something does light up, it means something.
