Bidirectional ODP and PDF conversion without Word or Excel dependencies. Forward ToPdfDocumentResult() calls expose the typed ODP-to-PowerPoint report in SourceConversionReports and PDF-layout diagnostics in Report; ConversionReports, HasLoss, and RequireNoLoss() cover both stages. PDF to ODP defaults to one rendered PDF page per slide for visual fidelity; use PdfPowerPointImportOptions.CreateEditableTables() when editable detected tables are the goal.
