PointerType

Remarks

⚠ A fact on the event rather than a convention about its id range. Before this existed, a finger and a mouse arrived as the same shape and were told apart only by which range PlatformInput had allocated their PointerId from — a rule written down in one file's comments and knowable nowhere else.

⚠ Unknown is zero, and that is deliberate rather than tidy. The value exists to be trusted at an arbitration point: touch-action governs touch and nothing else, so a reader that applied it to a mouse would stop a map responding to a mouse drag, which no browser does. A default of Mouse would make every producer that has not been updated claim to be a mouse, which is exactly the failure a default cannot be allowed to have — an unset field must read as "nobody said", not as an answer.
