Day 7 完了
実装内容: 1. 依存ライブラリ追加: axios, lucide-react, clsx, tailwind-merge 2. APIクライアント作成: frontend/src/lib/api.ts - JWT認証対応 3. ログイン画面作成: frontend/src/app/login/page.tsx - 日本語UI 4. レイアウト更新: frontend/src/app/layout.tsx - Noto Sans JP追加 5. JWTエンドポイント追加: backend/keinasystem/urls.py にJWT URL追加 テスト結果: - ログインAPI (/api/auth/jwt/create/) → HTTP 200 OK - テストユーザー: admin / password123 ブラウザで http://localhost:3000/login にアクセスして動作確認できます。 次の工程に移りますか？
