    // or just fail to find the package.
    // We can't easily capture cargo's stderr here because Command::new("cargo") inside the binary
    // inherits stdout/stderr by default unless captured.
    // In src/bin/creator/run.rs: Command::new("cargo").status()? inherits.
    // So the output won't be in `status.stderr` of the creator process unless we change run.rs to capture.
