/* =========================================================
   App da Júlia — Sílabas e Palavras
   Tema: animais fofinhos
   Considerações TEA:
   - Paleta pastel suave (não satura)
   - Animações lentas (250ms+) e nunca pulsando rápido
   - Sem flashes, sem cores piscando
   - Botões grandes (mínimo 64px de altura)
   - Foco e contraste claros, ícones consistentes
   - Estrutura visual previsível (sempre o mesmo lugar)
