 # Vendored from: https://github.com/nayuki/QR-Code-generator/blob/master/python/qrcodegen.py
 # Used by maintenance_supporter for QR code generation (helpers/qr_generator.py).
+# Local change: the byte helpers are annotated bytearray (what they build and
+# return) — mypy --strict no longer treats bytearray as bytes. Code unchanged.
