/* ============================================================
   ORDERS SYSTEM — tokens and primitives

   The world: quiet surfaces, generous air, one accent, and type
   doing the work that borders used to do. Nothing is decorated.
   A control looks pressable because of its shape and its fill,
   not because something was drawn around it.

   Rules the rest of the stylesheet obeys:
     · One accent. Colour means state, never brand mood.
     · Hairlines, not borders. A rule is 1px of near-nothing.
     · Elevation is one soft shadow, used on things that float.
     · Radius is consistent: 8 for controls, 14 for surfaces.
     · Figures are tabular, always. Money that shifts width as
       its digits change is software that does not respect money.
