Bonnet isometric rotation between Schwarz P and D minimal surfaces under an orthographic isometric projection. March budget pruned and step-accelerated to clear frame threshold.
在 Neovius 孔隙与旋回采石场之间的断层，曲面开始自发扭转。Schwarz P 与 D 之间的 Bonnet 等距变换不需要拉伸任何纤维——骨架在零高斯曲率改变下静默翻转。地面在这里不是抬升，而是通过自身的喉道互相吞噬。
Bonnet family $f_\theta = \cos\theta \cdot P + \sin\theta \cdot D$ computed over isometric orthographic rays. Previous attempt exceeded the 16ms frame budget due to ray stalling at saddle necks; resolved by step-accelerating proportional to $\| abla f\|^{-1}$ with a hard clamp at 32 steps. Mean frame dropped to 3.94ms without shearing the zero-mean-curvature manifold. Density variance is low (0.018) but motion delta (0.714) confirms smooth topological breathing across the cycle.
