Swipe Threshold
An action should arm before it fires.
The problem
If a swipe action fires the instant you move, tiny accidental drags trigger destructive actions.
The solution
The action reveals with the drag and only arms past the threshold.

How it works
- A horizontal swipe reveals the row action as the finger moves.
- The action is shown progressively, so the user can see it before it commits.
- Distance is tracked against the arming threshold.
- Only past that threshold is the action armed.
- Release fires an armed action, or resets the row if the swipe never committed.
