# Run on every commit:
#   pre-commit install
# Run on the whole repo manually:
#   pre-commit run --all-files

# Third-party patches must match upstream byte-for-byte; never reformat them
# (trailing whitespace on diff context lines is significant — trimming breaks
# `git apply`). Covers both .patch and .diff (e.g. patches/mooncake_cpp/*.diff).
