Design

この issue には説明がありません。

The issue title 'Design' is vague and the body is empty; a newcomer would need to ask the maintainers for clarification on what design work is needed. Start by checking the repository structure to understand the frontend project's current design system or UI components. Look for any existing design documentation or related issues to infer scope.
