 * The {@link MasterShowcaseExample} kitchen-sink report emitted as a PowerPoint
 * deck: the same composition, built once through the shared session config and
 * written through the fixed-layout PPTX backend via
 * {@link DocumentSession#buildPptx(java.nio.file.Path)}. Each resolved page becomes one
 * identically-sized slide, so the multi-page report opens in PowerPoint as an
 * editable copy of the PDF — rich text, the advanced table, header/footer
 * chrome, and barcodes arrive as native shapes and text frames; the rotated,
 * clip-masked seal is the one region that lands as a pixel-exact picture.
