react-native-pdf

real PDF rendering via browser-native <embed type="application/pdf"> — uses the browser's built-in PDF viewer (Chromium PDFium / Firefox pdf.js / Safari PDFKit) with full scrolling, zoom, search, and selection UI for free. page prop honored via #page=N URL fragment per PDF Open Parameters spec. ref.setPage(n) and ref.reload() implemented. onLoadComplete fires with numberOfPages=0 (unknown — embed exposes no load event with metadata). Works for the 95% of consumer code that wants to display a PDF.
