# Runtime dependencies — minimum version bounds for direct dependencies.
#
# These bounds match pyproject.toml and are compatible with Python 3.10+.
# pip will resolve the correct transitive versions for your Python version.
#
# To install:
#   pip install -r requirements.txt
#
# If you need a fully-pinned lockfile for exact reproducibility (Python 3.11+):
#   pip install pip-tools
#   pip-compile pyproject.toml --output-file requirements-lock.txt
