Defined in:
lib/idml/composition/add_page_from_idml.rb

Overview

Append a page (and its supporting spreads + stories) from a source package into a destination. Follows the same immutability pattern as InsertIdml: prefixes both sides, returns a new Package.

This is a structural implementation: it copies the source's spread files into the destination's spreads list and updates designmap to reference them. Page-item geometric reflow is deferred.
