# Upstream sources

These files are unmodified reference material, not a runtime dependency.

The local `package.json` is repository-owned loader metadata. It marks the
vendored UMD implementation as CommonJS so a parent ESM package cannot change
how Node.js loads it. The upstream files below remain byte-for-byte unchanged.
