*MERGE CURVES TO GET COMPRESSION AND TENSION COMBINED RATES*
============================================================

Merges two sets of curves (e.g. compression and tension rate curves) into a single combined curve by joining their rate data. Use this worker when you need to concatenate or pair compression and tension curves into a unified representation for downstream material or structural analysis.

When to use

Classification: **process**.

     - First set of curves to merge (e.g. compression rate curves); accepts multiple curve vectors. Leave empty if only one curve set is available.
