+### Added
+- The bundled PDF.js (`pdf.mjs` and `pdf.worker.mjs`) now ships with `core-js`
+  polyfills for five newer JavaScript APIs the PDF.js 6 build relies on —
+  `Map.prototype.getOrInsertComputed`, `Promise.try`, `Promise.withResolvers`,
+  `Uint8Array.prototype.toHex`, and `URL.parse`. Without them the viewer threw on
+  startup in browsers that predate those APIs; it now runs on those older engines.
+  The polyfills are injected into the two bundles at build time with esbuild, so
+  consumers pull in nothing new at runtime — `core-js` stays a build-only
+  dependency. Thanks to @delagen for the contribution. (#379)
