 /**
- * Errors Page - #44 錯誤追蹤頁面
- * ==============================
- * Phase 10: Sentry + OpenClaw + UI 整合
- *
- * Nothing.tech 視覺規範:
- * - 純白底色 (bg-white)
- * - 極細淺灰邊框 (border border-gray-200)
- * - 無圓角或微圓角 (rounded-sm)
- * - 嚴禁陰影 (shadow-none)
- *
- * 佈局:
- * - 左側: 統計卡片 + 趨勢圖
- * - 右側: 問題列表
- *
- * i18n: 100% next-intl，零硬編碼
- *
- * 建立: 2026-03-26 (台北時區)
- * 建立者: Claude Code (#44 Error UI)
+ * Errors Page — Sprint 5: 內容抽取到 ErrorsPanel
