*CURVE VARY Y AT X*
===================

Takes a base curve and sweeps the Y value at a specified X location across a defined range (min, max, step), producing a family of modified curves. Use this worker to generate parametric curve variants for sensitivity studies or DOE sweeps where only a single Y anchor point is varied.

     - 
     - The source curve (X-Y vector) that serves as the template; the Y value at the specified X position will be varied across all generated variants.
   * - X
     - x
     - scalar
     - 0
     - 
     - The X-axis location at which the Y value is pinned and swept; defaults to 0.
   * - Min Y
     - min_y
     - scalar
     - 0
     - 
     - The minimum Y value to use at the specified X location when generating the sweep; defaults to 0.
   * - Max Y
     - max_y
     - scalar
     - 1
     - 
     - The maximum Y value to use at the specified X location when generating the sweep; defaults to 1.
   * - Step Size Y
     - step_sizefor_y
     - scalar
     - 0.1
     - 
     - The increment between successive Y values in the sweep (e.g. 0.1 produces values 0.0, 0.1, 0.2 … up to max_y); defaults to 0.1.
