   HitPlay – Estilos del juego
   Psicología del color:
   · Fondo índigo/violeta profundo: escenario de concierto, foco y misterio;
     hace resaltar los colores saturados de las respuestas.
   · Ámbar/naranja (#ffb020): energía y urgencia → botones de acción.
   · Rojo/azul/amarillo/verde en respuestas (código Kahoot): decisiones
     rápidas por color y forma, no solo por texto.
   · Verde lima y dorado: recompensa, victoria, dopamina.
