C3D-0088 · Populate CURVE DELTA OFF with the ARC/CHD/RAD format [MK-CURVE-STYLE3] done

CopyFrom collided on the source style name, so this writes the text component contents, height and offsets directly from Delta over Length and Radius into CURVE DELTA OFF and sets the Delta component invisible. Contains no erase; verifies the components and their visibility afterwards.

C# payload

// Populate "CURVE DELTA OFF" (already created by C3D-0087, currently empty of the right content).
//
// CopyFrom threw "Duplicated Name" because the copied style carries the SOURCE's name and
// collides in the collection. So do not CopyFrom - write the text component contents directly,
// taken verbatim from the source style's components read in C3D-0083.
//
// NO ERASE. The existing style is opened and edited in place.
