A pointer-up after a drag no longer counts as a click (dragging flag + press-to-release distance within the existing tolerance), so drag -> release -> click cannot trigger a reset anymore. PaintHud prefab: pointer tolerance 4 px, HalfLambert default back to 0.5. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>
