# Pre-commit hooks for FreePDFEditor contributors (§13.2). Install with
# `pre-commit install` after cloning. CI runs the same hooks so a missed local
# run is caught, not lost.
# Pre-commit itself is optional; the hooks it runs (clang-format, gitleaks,
# reuse) are the contract. If a contributor doesn't use pre-commit, CI still
# enforces all of these.
