Phase-B first pass was stiff/awkward — the turn whipped ~180° in ~0.7s while the turn clip ran 2.5s (fighting), and a flat fish spun that fast went edge-on. Rework: - U-turn now runs over the clip's duration (~2.4s), smootherstep ease-in-out, banks in/out (roll), glides the arc instead of stopping — heading + animation move together. - Calmer: slower cruise (0.26), fewer modes (cruise/rest, dropped jerky darts), longer timers, gentle continuous roll/pitch body sway so cruising isn't rigid. - New "preview clip" tuner control: freeze locomotion + loop any raw clip broadside — proves the animation itself is fluid (isolates engine vs asset).
