*CONVERT COMPLEX CURVE TO DYNAMIC STIFFNESS*
============================================

Converts a complex-valued curve (real + imaginary parts) into its dynamic stiffness representation. Use this worker when frequency-domain compliance or impedance data needs to be expressed as dynamic stiffness (K* = F/X) for NVH post-processing workflows.

     - Complex-valued frequency-domain curve (real and imaginary components as a vector pair, e.g. compliance or mobility vs. frequency in Hz); leave unconnected if no upstream complex curve is available — output will be empty.
