PDF.js 2.16.105 legacy build (Apache-2.0; see LICENSE).
pdf.min.js and pdf.worker.min.js remain the pinned upstream files.

pdf.worker.compat.js is a generated CEP9/Chromium61 derivative, not a new PDF.js version.
scripts/prepare-pdfjs-cep9.js expands five Unicode-property tokens in two regular
expressions to Unicode17 codepoint ranges, and prepends client/cep-runtime-compat.js.
This permits both real workers and PDF.js main-thread fallback without replacing
the global RegExp constructor. Newer engines keep the original upstream worker.

Regenerate with the pinned Node24/Unicode17 build runtime:
  node scripts/prepare-pdfjs-cep9.js
Verify reproducibility and all category codepoints:
  node tests/pdfjs-cep9-worker.test.js
