 * Pass exactly one of `wasmUrl` or `wasmBinary`.
 *
 * - `wasmUrl`: absolute URL of pdfium.wasm. Bundlers like Vite (`?url`) and
 *   Webpack 5 (`new URL(..., import.meta.url)`) produce absolute URLs in
 *   production. The worker streaming-instantiates from the URL.
 * - `wasmBinary`: raw bytes of pdfium.wasm. Useful when you already have the
 *   bytes (cached in IndexedDB, fetched via custom auth, etc.). The buffer is
 *   transferred to the worker — pass a copy if you need to keep using it.
