The ball is tested as a circle against every alive block using a clamped nearest-point distance, so corners register honestly instead of in a square halo.
Overlap on X is compared against overlap on Y. The shallower axis is the one the ball just crossed — flip dy on a shallow Y overlap, dx on a shallow X overlap.
Only the nearest candidate resolves per sub-step, the ball is pushed out along the resolved axis, and speed is renormalised — no tunnelling, no block chaining, no stuck ball.
Contact offset −1…+1 maps to a −60°…+60° exit vector, plus a slice of paddle velocity for spin. Hitting the paddle's side faces mirrors dx instead.
