LIGHT TIMING: the hold saves the set; what is under a cue includes the stem's lag

- After moving cues, the hold clicks File > Save Live Set in Live (System Events; osascript has
  Accessibility on the Tracks Mac), only when the set open in Live is the one checked
- "Under the cue" now looks from 10 ms before to 25 ms after it: a cue on a hit whose stem starts
  10-15 ms after the grid read as a quiet spot (Name Above All Names 737.1.1 was moved by mistake
  and has been put back)
