-Format embedded shell snippets using the shfmt hook configured in
-.pre-commit-config.yaml.
-
-Two shapes are recognised:
-
-* YAML workflow/action files: literal block-scalar runs (`run: |`) and
-  single-line runs (`run: some command`). A single-line run is upgraded to
-  a `run: |` block scalar if shfmt's output spans multiple lines.
-
-* Markdown files: ``` ```bash ``` fenced code blocks.
-
-Any block that shfmt cannot parse is skipped with a warning on stderr, so
-the file is left untouched and surrounding blocks still get formatted.
-
-For each occurrence the body is dedented, written to a temp .sh file,
-formatted via `pre-commit run shfmt --files <temp>` (falling back to
-`prek`), then re-indented and written back in place.
-
-When invoked without arguments, every .yml/.yaml under .github/ plus every
-.md file in the repo is scanned. When invoked with file arguments (the
-pre-commit case), only those files are processed.
