A heavy bag hangs in the center of the canvas with a chain running up to the top. Sharp motion above an energy threshold counts as a punch, shaking the bag and adding points. Chain hits within one second for combo multipliers up to ×8. Detection is "motion energy spike" — no aiming required, so any framing works.
