/* Aata (ಆಟ): brain games for Raji, on a tablet.
   Layout: a calm home of large tiles (today's three first, then four groups); each game fills the
   screen under one big top bar. One light world on purpose: warm cream paper, deep teal for actions,
   marigold only for celebration. Baloo Tamma 2 covers Kannada and Latin in one friendly face.
   Senior-friendly: text 20px and up, touch targets 56px and up, no red "wrong" states, no timers. */
