PDF.js 6.4.299 (Mozilla), Apache-2.0.
Source: https://github.com/mozilla/pdf.js
Distribution: https://www.npmjs.com/package/pdfjs-dist/v/6.4.299

Vendored from the official pdfjs-dist 6.4.299 npm tarball, without running scripts.
legacy/build/pdf.mjs and pdf.worker.mjs are copied as pdf.js and pdf.worker.js
so WordPress servers serve JavaScript MIME types without extra configuration.
Both files remain ES modules. The cmaps, standard_fonts, wasm and iccs folders
are copied unchanged, including their licenses. Source maps are omitted.
The renderer is loaded only when a PDF design is selected; no public CDN is used.
