22/// for the same parameters and constant input the returned `v` trace, spike
23/// count, and final `(v, u)` state are bit-identical to the Python RK4 reference
24/// (the NeuroML right-hand side `k (v-vr)(v-vt)/C` is exact arithmetic — products,
25/// a sum and a division, no transcendental functions).
