/* One back control across EventMe.
   At rest: a calm round glass circle with a white arrow, easy to find but quiet.
   On hover, press or keyboard focus: the EventMe red glass glow.
   Icon only buttons use the circle directly; labelled ones ("All services", "Profile",
   the Community logo) wrap the circle in .em-back-ic / .comm-back-ic.
   Windows that sit on top of the page keep their X to close. */
