PDFURL loads a URL-hosted document; Base64Data embeds the bytes directly (an optional data:application/pdf;base64, prefix is stripped automatically).
ShowToolbar, ShowPageNav, ShowZoomControls, ShowDownload, ShowPrint and ShowSearch each show or hide one control group.
InitialPage sets the starting page; Zoom accepts auto, page-width, fit, a percentage or a numeric factor.
Theme (TsgcHTMLPDFViewerTheme: pvLight, pvDark) switches the toolbar and canvas color scheme.
PDFJSLibURL/PDFJSWorkerURL default to the jsDelivr CDN build; override both to self-host the library.
Width/Height size the viewer; DownloadFileName names the file saved by the Download button.
