• UI組件模組化:
  - FlashcardDetailHeader.tsx: 標題區組件 (75行)
  - FlashcardContentBlocks.tsx: 內容區塊組件 (139行)
  - 移除標題區複雜UI: 62行標題、統計、TTS邏輯

• 詞卡詳情頁面優化:
  - 原始: 737行 → 當前: 536行 (減少27.3%)
  - 架構: 3個Hook + 2個UI組件完成
  - 編輯邏輯: 統一handleEditChange處理函數

• 第三階段進展:
  - UI組件模組化基礎建立
  - TTSButton集成，提升組件一致性
  - 為後續完整組件替換奠定基礎

• 累計兩大頁面重構成果:
  - 主頁面: 878行 → 305行 (減少65.3%)
  - 詳情頁面: 737行 → 536行 (減少27.3%)
  - 總體架構: 6個Hook + 7個組件體系

+### 🎯 **第三階段計劃: UI組件模組化** - 2025-10-01 23:15
+
+#### **下一步重構方向**
+基於分析，詞卡詳情頁面(593行)還有大量UI組件可以拆分：
+
+1. **FlashcardDetailHeader** (~75行) - 標題區、統計數據、TTS按鈕
+2. **FlashcardContentBlocks** (~120行) - 翻譯、定義、例句區塊
+3. **FlashcardImageSection** (~60行) - 圖片展示、生成控制
+4. **FlashcardActionButtons** (~50行) - 收藏、編輯、刪除按鈕
+
+#### **預期第三階段效果**
+- **目標**: 593行 → ~350行 (再減少40%+)
+- **新增**: 4個專責UI組件
+- **總體**: 詞卡詳情頁面達到50%+優化
+
+#### **✅ 第三步: UI組件拆分進行中** - 2025-10-01 23:15
+- **FlashcardDetailHeader.tsx**: 已創建並整合 (75行) ✅
+- **移除標題區UI**: 57行複雜標題渲染邏輯 ✅
+- **頁面持續優化**: 593行 → 536行 (再減少9.6%) ✅
+
+#### **📊 詞卡詳情頁面累計優化結果**
+- **原始檔案**: 737行 (嚴重技術債務)
+- **當前狀態**: 536行 (健康水準)
+- **累計減少**: 201行 (**總計減少27.3%**)
+- **架構模組化**: 3個Hook + 1個Header組件
+
+#### **✅ 第四步: 內容區塊組件創建完成** - 2025-10-01 23:20
+- **FlashcardContentBlocks.tsx**: 已創建 (139行) ✅
+- **整合**: 翻譯/定義/例句/圖片/同義詞區塊 ✅
+- **優化**: 使用TTSButton組件，提升一致性 ✅
+
+#### **🎯 第三階段剩餘計劃**
+基於當前架構，還有優化空間：
+1. **FlashcardContentBlocks集成** - 替換主頁面內容區 (~150行)
+2. **FlashcardActionButtons** - 操作按鈕組獨立 (~50行)
+3. **詞卡資訊區塊** - 詳細信息組件 (~40行)
+
+#### **📊 第三階段預期最終效果**
+- **當前**: 536行 (已減少27.3%)
+- **集成後預期**: ~400行 (目標減少35%+)
+- **新增組件**: 總計7個專責組件完成
+
+### 📈 **第三階段優化潛力**
+- **短期**: 繼續拆分UI組件，達到50%代碼減少
+- **中期**: 建立測試體系，提高代碼品質
+- **長期**: 應用同樣模式到其他大型組件
