Office Transform

Turn a structural selection of an Office/PDF document into a new derived file.

Two invariants hold for every operation:

1. The source file is read-only. Every result is a new file; both scripts refuse to write to the source path or overwrite an existing file. Never work around this with ad-hoc shell edits to the original.
2. Anchors are structural. Selections address the document's own coordinates — worksheet + A1 range, body-level paragraph ordinal, one-based page number — never screen or DOM positions.
