Vendored as-is (unmodified) so QR codes generate locally with zero
external dependencies — no Composer, no runtime network call to a
third-party QR API. Verified in this project by generating a PNG for
a sample event URL and decoding it back with an independent scanner
(zbar) to confirm round-trip correctness.
