Thanks, this is a good catch. However, as it is a change in style, it should be applied only to Black's preview style.

Guidance on that probably would have been useful, but I believe I may have figured it out

There's a CI failure that looks unrelated to your change, probably due to a typing change in a dependency. I can look into it over the next few days.

I fixed the last lint error by updating the schema

<summary>psf/black (black)</summary>

### [`v25.1.0`](https://github.com/psf/black/blob/HEAD/CHANGES.md#2510)

[Compare Source](psf/black@24.10.0...25.1.0)

##### Highlights

This release introduces the new 2025 stable style ([#&#8203;4558](psf/black#4558)), stabilizing
the following changes:

-   Normalize casing of Unicode escape characters in strings to lowercase ([#&#8203;2916](psf/black#2916))
-   Fix inconsistencies in whether certain strings are detected as docstrings ([#&#8203;4095](psf/black#4095))
-   Consistently add trailing commas to typed function parameters ([#&#8203;4164](psf/black#4164))
-   Remove redundant parentheses in if guards for case blocks ([#&#8203;4214](psf/black#4214))
-   Add parentheses to if clauses in case blocks when the line is too long ([#&#8203;4269](psf/black#4269))
-   Whitespace before `# fmt: skip` comments is no longer normalized ([#&#8203;4146](psf/black#4146))
-   Fix line length computation for certain expressions that involve the power operator ([#&#8203;4154](psf/black#4154))
-   Check if there is a newline before the terminating quotes of a docstring ([#&#8203;4185](psf/black#4185))
-   Fix type annotation spacing between `*` and more complex type variable tuple ([#&#8203;4440](psf/black#4440))

The following changes were not in any previous release:

-   Remove parentheses around sole list items ([#&#8203;4312](psf/black#4312))
-   Generic function definitions are now formatted more elegantly: parameters are
    split over multiple lines first instead of type parameter definitions ([#&#8203;4553](psf/black#4553))

##### Stable style

-   Fix formatting cells in IPython notebooks with magic methods and starting or trailing
    empty lines ([#&#8203;4484](psf/black#4484))
-   Fix crash when formatting `with` statements containing tuple generators/unpacking
    ([#&#8203;4538](psf/black#4538))

##### Preview style

-   Fix/remove string merging changing f-string quotes on f-strings with internal quotes
    ([#&#8203;4498](psf/black#4498))
-   Collapse multiple empty lines after an import into one ([#&#8203;4489](psf/black#4489))
-   Prevent `string_processing` and `wrap_long_dict_values_in_parens` from removing
    parentheses around long dictionary values ([#&#8203;4377](psf/black#4377))
-   Move `wrap_long_dict_values_in_parens` from the unstable to preview style ([#&#8203;4561](psf/black#4561))

##### Packaging

-   Store license identifier inside the `License-Expression` metadata field, see
    [PEP 639](https://peps.python.org/pep-0639/). ([#&#8203;4479](psf/black#4479))

##### Performance

-   Speed up the `is_fstring_start` function in Black's tokenizer ([#&#8203;4541](psf/black#4541))

##### Integrations

-   If using stdin with `--stdin-filename` set to a force excluded path, stdin won't be
    formatted. ([#&#8203;4539](psf/black#4539))
