/**
 * `<LensPDFDemo>` — the marketing-chrome wrapper around {@link LensPDF}.
 *
 * `<LensPDF>` is the complete viewer. `<LensPDFDemo>` is a thin layer
 * on top of it that adds the upload chrome — URL bar, drag-and-drop,
 * file picker, and empty state — and feeds the resulting PDF URL into
 * `<LensPDF>`. It powers the public showcase at lenspdf.com so
 * reviewers can drop arbitrary PDFs into the page without a host.
 *
 * **Most consumers should use {@link LensPDF} directly** — it's the
 * one-liner production drop-in:
 *
 * ```tsx
 * <LensPDF pdfUrl="/proofs/abc.pdf" workerSrc={pdfWorkerSrc} />
 * ```
 *
 * Reach for `<LensPDFDemo>` only when you want the built-in upload
 * affordances (a standalone demo page, an internal scratch tool).
