二、界面美化特色

1. 現代UI設計

   • 采用扁平化設計風格
   • 使用系統圖標符號（📁📂🔒）提升直觀性
   • 自定義QSS樣式表實現漸變按鈕和圓角邊框

2. 交互優化

   • 實時路徑顯示
   • 動態進度條反饋
   • 狀態標簽提示當前操作階段
   • 按鈕禁用狀態防止重復操作

3. 安全增強

   • 密碼強度驗證（至少8位）
   • 密碼輸入掩碼顯示
   • 元數據文件獨立存儲（避免密碼泄露）

4. 響應式布局

   • 固定窗口尺寸防止變形
   • 智能間距控制
   • 組件對齊優化

三、使用說明

1. 選擇文件/文件夾
2. 輸入8位以上加密密碼
3. 點擊加密壓縮按鈕
4. 查看生成的.zip文件和同名的.json元數據文件
