- The timeline brings launches up as the time passes them, offers play
  speeds from real time to a week a second, and plays smoothly, holding only
  when the next weather frame has yet to load, with a spinner by the time
  while it waits. The time rides in a bubble over the handle. The track zooms
  with a scroll or a pinch, drags along, and goes to the time under a tap, on
  a phone as on a desktop. Zooming out on the globe stops while the globe is
  still in view instead of leaving it a speck (samehkhamis, #1513).
