 `uv.lock` is a human-readable TOML file but is managed by uv and should not be edited manually.
 There is no Python standard for lockfiles at this time, so the format of this file is specific to uv
 and not usable by other tools.

+    Recently Python standardized the lockfile format with `pylock.toml`.
