/* SocialBlink — página de Proceso.
   Idea: el proceso se recorre con él. Con el scroll, el personaje camina por un suelo y se detiene en
   las cuatro estaciones; en cada una se convierte en su pose y hay algo que probar.
   - Sin JS o con movimiento reducido: los pasos se leen uno debajo del otro (cada escena completa).
   - Con JS y movimiento (.ps-journey.is-live): el escenario se queda fijo, las escenas se desplazan
     según --sp (posición en el recorrido, 0…3, la fija js/proceso.js) y el texto del paso activo aparece. */
