   VUELVA USTED MAÑANA — Efectos de presentación (paquete P6)
   Capa fx: lo que js/ui-fx.js pone y quita al vuelo.
     · vuelo a la bandeja (.fly-item) y llegada (.slot.arrived)
     · respuesta al toque (.hs.hs-tapped, .tap-ring)
     · inactividad (.hs.glint, #btnHint.nudge, .fx-halo)
     · pósits de primera vez (.coach)
     · final de temporada (.finale, .fx-confetti, body.finale-on)
     · salida de los modales (.modal-ghost, .fx-conforme)
   Solo se animan transform/opacity y las propiedades sueltas
   translate/scale/rotate; nada es infinito. Con movimiento reducido
   (la base fuerza 0,01 ms en toda animación) cada efecto tiene un
   equivalente estático que js/ui-fx.js mantiene el tiempo que toca.
   Fotogramas con prefijo fx-.
