Pinch is a pointer.
Study the hand-pointer boundary as a deterministic desktop harness: a target ray finds the nearest mesh, pinch drives button states, and drag ownership is attached one frame later before returning to the original parent.

Connect, aim, and pinch the orange or pink button; select a cube to exercise deferred hand-pointer attachment.
Button states are [none, hovered, pressed]; draggable states are [detached, hovered, to-be-attached, attached, to-be-detached].
Desktop simulation verifies the pointer state machine and ownership policy; native hand joints, pinch poses, and headset frame timing remain hardware-gated.
The VR button requests hand-tracking. This page does not fabricate an immersive session; its desktop harness reuses the same hit, pinch, button, and drag boundaries for study.
