  1. Lower is better for HD95/AVE. Latency per slice on one A100 (AMP). †/‡ significantly worse than A0 (Wilcoxon, Holm).
  2. A1 = no shape-aware loss (λ2 = λ3 = λ4 = 0); A2 = no snake (T = 0); A3 = snake only (no implicit regression); A4 = Dice + CE only (no boundary term); A5 = no curvature smoothness (λ3 = 0).
