EnsureDeviceBuffers_Scalar2D Subroutine

  2. SELF_Scalar_2D
  3. EnsureDeviceBuffers_Scalar2D

public subroutine EnsureDeviceBuffers_Scalar2D(this)

Grow each device buffer to hold the current logical array, reusing the existing allocation when the bytes already fit (AMR Stage 6b). A device pointer carries no shape, so unlike the host side no remapping is needed - only a byte-capacity check.
