Summary

Merge two adjacent paragraphs in the same story. The first paragraph keeps its pPr; the second paragraph is removed. Rejects when either paragraph carries a w:sectPr or when their numbering definitions differ. Available on v2-backed sessions only; v1-backed sessions currently return CAPABILITY_UNAVAILABLE.
