   scrollcraft.css: the taste floor
   ----------------------------------------------------------------------------
   Two layers, and the split matters:

     TOKENS   what you override per brand. Colour roles, the type ramp, the
              spacing scale, elevation, motion. A brand is ~12 values.
     DEVICES  what the engine drives. Do not restyle these to taste; they are
              the mechanism. Style your own markup instead.

   Nothing here draws a "component". There are no card, badge, or pill classes,
   because a stylesheet that ships those is how every page built on it ends up
   with the same shapes. You get a floor and a vocabulary; the composition is
   yours.
