A dedicated saved-edition planner for handbound books: balanced or equal signatures, complete front/back folio pairs with blank pages, persistent reference-copy checks, measured-spine overrides, edition stock and covering takeoff, and matching production PDF/CSV exports. Existing workshop records remain available. Saves are immediate and atomic, unreadable stores are protected, and workshop PDFs now preserve all records and long notes. Offline guide summaries now show their full text.
