[M2-S1] Swing the chair: alternating sweeps with a slight recoil #39

User story

As a player, I want to swing the chair back and forth, so that fighting with furniture feels quick and a little silly.

Acceptance criteria

• Tap Act: side sweep A; tapping again plays sweep B (the return swing); each ends in a 2-frame recoil
• Hitbox on the contact frames only; 60 ms hit-stop, spark and knockback on hit
• A light weapon: no ground crack, no shockwave
