When `authenticate_user` is called with a username that doesn't exist in the database, we still run `verify_password` against a dummy hash.

This ensures the endpoint takes roughly the same amount of time to respond whether the username is valid or not, preventing **timing attacks** that could be used to enumerate existing usernames.

It would be very little effort from the person submitting the PR (an LLM prompt) that generates a large amount of effort on our side (carefully reviewing code).

Please don't do that.

We'll need to block accounts that spam us with repeated automated PRs or comments.

/// info | 매우 기술적인 세부사항

**참고**: 이는 매우 기술적인 세부사항이라 아마 **그냥 건너뛰어도 됩니다**.

`APIRouter`는 "mount"되는 것이 아니며, 애플리케이션의 나머지 부분과 격리되어 있지 않습니다.

이는 OpenAPI 스키마와 사용자 인터페이스에 그들의 *path operations*를 포함시키고 싶기 때문입니다.

나머지와 독립적으로 격리해 "mount"할 수 없으므로, *path operations*는 직접 포함되는 것이 아니라 "clone"(재생성)됩니다.
