   Kids Planet — styles

   Look: soft-3D illustration style on a warm cream page with
   static pastel "blob" decorations and pastel gradient cards
   (modeled on the provided design mockup). Icons are Microsoft
   Fluent Emoji 3D images rendered via .pic (sized in em so they
   drop in anywhere text-emoji used to be).

   Motion stays research-grounded:
   - Functional animations in the 100–500 ms band (NN/g).
   - Page decorations are fully static — zero competing motion
     during play (NN/g peripheral-motion findings, WCAG 2.2.2).
   - Touch targets ≥ 72 px, generously separated (Sesame ≥ 2 cm).
