   FINAL DESIGN. Warm cream canvas, white panels, generous
   spacing, soft rounded corners, one terracotta accent,
   SVG icon system (see shell/app/icons.tsx).

   ONE FILE = THE WHOLE LOOK. Edit the token block below and
   every screen in the system follows. Never write per-screen
   colours; always use the classes defined here.
