Replaces a single additive steering vector with a learned, concept-conditioned nonlinear velocity field over activation space, integrated via multi-step forward Euler; ordinary linear steering (h'=h+alpha*v) is recovered as the degenerate one-step, position-invariant special case.

Effective concept steering needs curved trajectories, not one linear directionmeasured
