- Keep the globe in view from orbit. Cesium's free look (Shift+drag) turned
  the camera in place, so a few drags from the whole-globe view left only
  stars, and the pose stayed in the share link. Free look now works only below
  1,000 km, and above it a drag that starts on the stars orbits the globe
  instead of turning the camera; a camera move that ends above it with no
  planet surface in view (inside the scope keyhole when the scope is on) turns
  straight down; and voice tilt and turns from orbit stop while the planet is
  still on screen and say so instead of reporting a turn they could not make.
  Thanks to [Chad Elliott](https://github.com/THEtheChad) for the review that
  closed the drag path and kept authored scenes framed (Manjunath,
