# Check-only: reports formatting issues without modifying the branch.
# The job fails (and annotates unformatted files) when `prettier --check`
# finds files that are not formatted, but it never writes, commits, or
# pushes anything back to the PR. Developers run `npx prettier@3 --write .`
# locally to fix the reported files.
