- The palm-down filter is off by default: the user's deliberate pinches,
  hand raised, read 0.90-0.99, like typing.
- Typing is told apart by the keyboard instead: the input relay sends the
  pointer helper "typing" on key presses, and it takes no pinch within
  POINTER_PINCH_TYPING (1 s) of one.
- Grips are still held to hands raised (POINTER_GRIP_BELOW, 0.35 m below
  the eyes); pinches aren't, since the user's own sat 0.35-0.45 m below,
  elbow resting.
- A grip doesn't begin with the thumb on the index tip: that's a pinch
  with the other fingers curled, which was taken for a grip.
- A pinch's point is the index and middle knuckles: the tips' midpoint
  moved 1-2 cm as the pinch opened, dragging every release off its press.
- ft-hands --gesture-log prints what the detectors measure, 10 times a
  second.

Pinches still aren't reliable enough to use; hand tracking is parked for
now in favour of the controllers.
