   Structural styles only. Every colour, size, space, radius and duration below
   is read from a semantic alias in tokens.css. A hex literal or a raw pixel
   colour value in this file is a defect — see tokens.css header.

   Layout dimensions not defined by the token system (page container widths)
   are plain values, chosen for a two-page marketing/placeholder surface,
   not the 1600px clinical work-surface grid tokens.css defines for the app.
