*SYNC THE X-POINTS OF TWO CURVES*
=================================

Synchronises the x-axis sample points of one curve to those of a reference curve by interpolation, using either a merged or reference x-point strategy. Use this worker whenever two curves must share a common x-grid before downstream comparison, arithmetic, or correlation operations.

Inputs
------

.. list-table::
   :header-rows: 1
   :widths: 20 20 20 20 20 20

   * - Label
     - ID
     - Type
     - Default
     - Required
     - Description
   * - Curve To Be Synced
     - curvetobesynced
     - vector
     - —
     - 
     - The primary curve whose x-points will be resampled to align with the reference; supply as a two-column (x, y) vector — this is the curve that is modified.
   * - Ref Curve
     - ref_curve
     - vector
     - —
     - 
     - The reference curve that defines the target x-grid; its x-points are used as the synchronisation template and its y-values are interpolated onto the new grid when 'reference' mode is chosen.
   * - Type Of Sync
     - typeof_sync
     - scalar
     - merge
     - 
     - Sync strategy: 'merge' combines x-points from both curves into a union grid (default), while 'reference' resamples the primary curve strictly onto the reference curve's x-points.
   * - Extrapolate
     - extrapolate
     - scalar
     - yes
     - 
     - Whether to extrapolate y-values beyond the original x-range when the target grid extends outside it; set to 'yes' (default) to extrapolate or 'no' to clamp to boundary values.

     - curve_sync_with_output_1
     - vector
     - The synchronised primary curve resampled onto the new common x-grid, returned as a two-column (x, y) vector with the same units as the input curve.
