/* ====================================================================
   ENDO GYM
   Idea: el traje de electrofitness. Una silueta con sus electrodos que
   se encienden de a uno, de arriba abajo, sobre la línea de un impulso
   eléctrico; el lema propio del gimnasio como titular. Tinta azulada,
   índigo, cian eléctrico y gris niebla. El único brillo es el de los electrodos.
