Vendored third-party libraries (for /diff/)

These are pinned, locally-served copies so the Diff Checker runs fully offline with no CDN/network calls (privacy + the site’s no-external-deps ethos). Downloaded, not hotlinked.

jsdiff — diff.js

• Version 5.2.0 (UMD build, dist/diff.js)
• License: BSD 3-Clause — https://github.com/kpdecker/jsdiff/blob/master/LICENSE (a copy is kept next to the file as LICENSE, and a header notice is prepended to diff.js)
• Kevin Decker’s text-diff implementation (Myers algorithm). Used for line-level and word-level diffing and for producing unified-diff patch text. Exposes window.Diff.

Note: PDF text extraction on /diff/ reuses the already-vendored pdf.js under assets/js/pdflib/ (Apache-2.0; see assets/js/pdflib/VENDOR-LICENSES.md).

To update: re-download the same files from the upstream release and bump the versions here.
