Feedback batch from a phone playtest: - Winning a game no longer auto-sweeps the court. The survivors stay and must be killed by hand (no new spawns, no scoring during the mop-up); only once the court is clear does play advance to the changeover / next game / set. Replaces sweepCourt() with a G.clearing gate + proceedAfterClear(). "CLEAR THE COURT". - Classic shamblers (a/b) now soak one splat-quality wound before they drop (shamblerHp=2) — swapping to new z_aw/z_bw wound skins that bleed the thin dynamic trickle plus a small impact pop. Only the runner stays one-shot glass; brute/boss unchanged. Ball, pellets and triple side-balls all respect hp. - Winning a SET shows a centered milestone card (a real pause) before the horde; one reusable drawCard() now backs both it and the reworded sudden-death card. - Player is no longer pinned to the baseline: free to advance up-court on keyboard (bounded at the net); touch keeps the baseline (drag is the serve-aim) and the horde/GUN burst re-brace there.
