/* ====================================================================
   CURVES RAFAELA
   Idea: el circuito en ronda es el dibujo. Doce estaciones alrededor
   de un círculo (fuerza llena, recuperación en aro); al cargar, la
   vuelta se dibuja una vez y el centro cuenta hasta 30 minutos.
   Fucsia, azul noche, rubor y un toque limón. Formas redondas, sin sombras.
