*SCALE THE Y-VALUES OF ALL CURVES BASED ON CONDITIONS OF THE X VALUE*
=====================================================================

Scales the y-values of one or more curves by a constant factor, but only at points where the x-value satisfies a specified condition (lt, lte, eq, gte, gt) relative to a target x value. Use this worker when you need conditional, x-range-filtered amplitude scaling across a batch of curves.

   * - Curves To Be Scaled
     - curvestobescaled
     - vector
     - —
     - 
     - One or more input curves whose y-values will be conditionally scaled; accepts a vector (list) of curve objects — leave empty only if downstream wiring supplies curves dynamically.
   * - Y Scale Value
     - y_scalevalue
     - scalar
     - 1
     - 
     - Dimensionless multiplicative scale factor applied to y-values at all qualifying points; defaults to 1.0 (no scaling).
   * - Condition For X
     - conditionfor_x
     - scalar
     - eq
     - 
     - Comparison operator that defines which x-points are eligible for scaling: 'lt' (<), 'lte' (≤), 'eq' (=), 'gte' (≥), or 'gt' (>); defaults to 'eq'.
   * - Target Value For X
     - target_valuefor_x
     - scalar
     - 0
     - 
     - The reference x-value used in the condition check (same units as the curve x-axis); only curve points satisfying condition(x, target) will have their y-values scaled; defaults to 0.
