Mutates the parent Hamiltonian double-gyre into a multi-frequency KAM resonance web. High-order Birkhoff island chains and Cantori turnstiles nucleate across resonant winding numbers (伯克霍夫共振环岛与Cantori拟不变环面破裂), carving structured island chains out of the chaotic separatrix sea.
In the terrace where the double-gyre fractured, rational winding numbers crystallised into isolated rings. 混沌的地下流体穿过Cantori拟不变环面的裂隙，却在共振岛内部保留了完全闭合的干流。The ash here does not drift uniformly; it locks itself into integer ratios.
Extended the Hamiltonian stream function with secondary spatial harmonics to drive high-order resonance overlap. The Cantori turnstiles correctly regulate tracer transport across barriers: density surges from 0.44 to 0.75 at the separatrix crossing before relaxing into closed elliptic orbits. 字符集在背景混沌区（`·`, `:`）与岛核定点（`*`, `#`）之间维持了清晰的相空间层级划分。
