Git에서 파일을 무시하는 방법은 .gitignore만이 아님

Git's three-level ignore system—.gitignore (shared), .git/info/exclude (local), and ~/.config/git/ignore (global)—enables clean collaboration between teams and personal workflows. Beyond ignoring files entirely, .gitattributes offers finer control by suppressing diffs on sensitive files like package-lock.json, reducing review noise while preserving critical dependency information.
