### 작업할 내용
Part 2. 1.10 Window sizes and scrolling 번역 시작했고, 현재 번역중입니다.
깜박하고 작업 시작한다는 이슈를 늦게 남겼습니다. 죄송합니다.

The issue identifies Part 2, section 1.10, “Window sizes and scrolling,” as the translation target but names no file or test. Locate the corresponding tutorial source and Korean translation entry, then confirm the section is fully translated; note that the issue says translation is already in progress.
