/* ============================================================
   IL GIOCO DELLE ROTELLE — stile locale
   Il resto (variabili, intestazione, footer, regole touch) arriva da
   css/kids-base.css.

   Il pezzo centrale è il CANVAS (#canvas-container), dove il motore
   disegna la catena di ruote: quella parte era già fatta bene e la si
   tiene. Tolto invece tutto il resto — i pulsanti radio, gli overlay a
   tutto schermo «Oh no ❌», gli stili inline — e messo lo scheletro
   standard delle app kids: modalità, HUD, opzioni a tocco, attestato.
