/* Soul portal. Design read: a companion app for a desk robot, phone first, playful but precise.
   Dials (taste-skill): VARIANCE 6, MOTION 4, DENSITY 4.
   Palette: cool porcelain like the robot's shell, ink, and ONE accent, the cobalt of its wheel
   rims. The eye blue (#7fc8ff) only ever appears inside the robot's face screen.
   Radius rule: stages 32px, cards 24px, inputs 14px, buttons and chips full pill. */
