 - Modernize type hints to use Python 3.10+ syntax (PEP 604: `X | Y` instead of `Union[X, Y]`)
 - Use built-in generic types (`list`, `dict`, `tuple`) instead of `typing.List`, `typing.Dict`, `typing.Tuple`

+- Replace black with ruff for faster linting and formatting. Configure ruff with line-length=120 and appropriate rule selections. Keep isort for import sorting with plone profile and force-alphabetical-sort. This modernizes the tooling stack for better Python 3.10+ support and faster CI runs.

-- **Formatting**: Black-compatible (max line length: 120)
-- **Import sorting**: isort with `force_alphabetical_sort = true`, `force_single_line = true`
-- **Type hints**: Use throughout (Python 3.10+ compatible)
+- **Formatting**: Ruff formatter (max line length: 120, target Python 3.10+)
+  - Configured in [pyproject.toml](pyproject.toml) under `[tool.ruff]`
+  - Rules: E, W, F, UP, D (with selective ignores for docstrings)
+  - Automatically enforced via pre-commit hooks
+- **Import sorting**: isort with plone profile, `force_alphabetical_sort = true`, `force_single_line = true`

+  - Use `list[T]`, `dict[K, V]` instead of `List[T]`, `Dict[K, V]`
 - **Path handling**: Prefer `pathlib.Path` over `os.path` for path operations
   - Use `pathlib.Path().as_posix()` for cross-platform path comparison
   - Use `/` operator for path joining: `Path("dir") / "file.txt"`
