## Goal
Spend review attention on design and correctness by making layout and mechanical style a solved, automated problem.

## Prerequisites
A formatter and a linter for each language in the repository, runnable from the command line with the configuration stored in the repository.

## Steps
1. Add an `.editorconfig` for indentation, line endings and trailing whitespace so that editors agree before any tool runs.
2. Choose one formatter per language and run it on the whole codebase in a single commit that contains nothing else.
3. Enable linter rules in stages: start with correctness rules (unused imports, undefined names, unreachable code), then add style rules the team accepts. PEP 8 itself says its guidance yields to consistency within a project.
4. Run both tools in the pipeline as a required check and, optionally, in a pre-commit hook.
5. Treat rule changes like code changes: propose, review, apply to the whole tree in one commit.

## Expected result
No review comments about spacing or import order; formatting diffs disappear from feature changes; new contributors get immediate, impersonal feedback from the tools.

## Limits and test basis
Formatters decide layout, not naming or structure; those remain review topics. A linter with hundreds of enabled rules produces noise that people learn to ignore. The cited tools are examples; the contract matters more than the tool.
