- Run `elm-format --yes src/` before every commit — it is the single authoritative formatter with no configuration options.
- Add `elm-format --validate src/` to CI to reject unformatted code on any pull request.
- Use `elm-review` with a `ReviewConfig.elm` to enforce project-specific rules such as no unused dependencies or banned patterns.
- Install the `elm-review/no-unused-variables` and `elm-review/no-unused-imports` rules to keep the codebase clean automatically.
