/* ============================================================
   SPACING, RADIUS, SHADOW & MOTION TOKENS — Work Excellence
   Generous whitespace, precise 4px rhythm, quiet elevation.
   Corners are gently rounded (structured, not soft/bubbly).
   Shadows are low-contrast and cool-toned — used sparingly to
   imply layered "systems", never for decoration.
