Excel workbooks have no natural "page" concept, so sheet navigation is built on LibreOffice's PDF export, which includes a bookmark/outline entry per sheet by default (verified end-to-end with a real 2-sheet workbook via convertToPdf + pdfjs-dist's getOutline/getDestination/ getPageIndex). The viewer reads that outline to show a bottom tab bar mirroring Excel's own sheet-tab convention, and the page indicator now shows which sheet is active. Falls back gracefully to a plain page list if a given export has no outline.
