   Tokens → base → components → sections → responsive

   Shape system (applied everywhere):
     interactive controls (buttons, chips, inputs) → full pill
     containers (cards, bento cells, dialog)       → --r (14px)
     images inside containers                      → --r-sm (10px)

   One accent (signal orange). Neutral greys, no warm/cool mixing.
   Motion only on transform/opacity, all of it gated behind
   prefers-reduced-motion: no-preference.
