*SCALE BASE CURVE TO STRAIN RATES*
==================================

Scales a quasi-static base stress-strain curve to multiple strain rates by referencing a set of strain-rate curves. Use this worker when building rate-dependent material cards (e.g., MAT_24) that require a family of scaled curves across different strain-rate levels.

     - 
     - The base quasi-static stress-strain curve (vector of X-Y pairs, stress in MPa vs. engineering or true strain) that will be scaled to each target strain rate.

     - vector
     - —
     - 
     - Collection of reference strain-rate curves (multiple vectors) that define the scaling ratios at each strain-rate level; each curve should share the same strain axis as the base curve.
