+# 快取清除機制說明
+
+## 📋 概述
+
+本系統實現了多層次的快取清除機制，確保使用者在程式更新後能夠立即獲得最新版本，避免因瀏覽器快取導致的問題。
+
+---
+
+## 🔧 實現方式
+
+### 1. HTML Meta 標籤（第一層防護）
+
+在 `index.html` 中添加了以下 meta 標籤：
+
+```html
+<meta http-equiv="Cache-Control" content="no-cache, no-store, must-revalidate" />
+<meta http-equiv="Pragma" content="no-cache" />
+<meta http-equiv="Expires" content="0" />
+```
+
+**作用**: 告訴瀏覽器不要快取 HTML 檔案，每次都從伺服器獲取最新版本。
+
+---
+
+### 2. JavaScript 版本檢測（第二層防護）
+
+在 `index.html` 中添加了智能快取清除腳本：
+
+```javascript
+const APP_VERSION = '2.4.0';
+const CACHE_KEY = 'app_version';
+
+// 檢查版本是否變更
+const storedVersion = localStorage.getItem(CACHE_KEY);
+
+if (storedVersion !== APP_VERSION) {
+    // 清除快取...
+}
+```
+
+**功能**:
+- ✅ 自動偵測版本變更
+- ✅ 清除 localStorage（保留重要資料如登入狀態）
+- ✅ 清除 sessionStorage
+- ✅ 清除 Service Worker 快取
+- ✅ 在 Console 顯示清除訊息
+
+**保留的資料**:
+- `adminAuth` - 管理員登入狀態
+- `VITE_SUPABASE_URL` - Supabase 連線 URL
+- `VITE_SUPABASE_ANON_KEY` - Supabase 金鑰
+
+---
+
+### 3. Apache .htaccess 設定（第三層防護）
+
+在 `.htaccess` 中添加了快取控制規則：
+
+```apache
+# 防止 HTML 檔案快取
+<FilesMatch "\.(html|htm)$">
+  <IfModule mod_headers.c>
+    Header set Cache-Control "no-cache, no-store, must-revalidate"
+    Header set Pragma "no-cache"
+    Header set Expires "0"
+  </IfModule>
+</FilesMatch>
+
+# 靜態資源使用 ETag 驗證
+<FilesMatch "\.(js|css)$">
+  Header set Cache-Control "public, max-age=2592000"
+  FileETag MTime Size
+</FilesMatch>
+```
+
+**作用**:
+- HTML 檔案：完全不快取，每次都獲取最新版本
+- CSS/JS 檔案：使用 ETag 驗證，檔案變更時自動更新
+- 圖片檔案：長期快取（1年），提升效能
+
+---
+
+## 🚀 使用方式
+
+### 發布新版本時
+
+1. **更新版本號**
+   
+   編輯 `index.html`，修改版本號：
+   ```javascript
+   const APP_VERSION = '2.4.1'; // 更新版本號
+   ```
+
+2. **重新建置**
+   ```bash
+   npm run build
+   ```
+
+3. **部署到 SiteGround**
+   
+   上傳 `dist` 資料夾的所有內容
+
+4. **完成！**
+   
+   使用者下次訪問時會自動清除快取並載入新版本
+
+---
+
+## 📊 快取清除流程
+
+```
+使用者開啟網站
+    ↓
+載入 index.html (不快取)
+    ↓
+執行版本檢測腳本
+    ↓
+版本號相同？
+    ├─ 是 → 正常載入
+    └─ 否 → 清除快取
+           ↓
+        保存重要資料
+           ↓
+        清除 localStorage
+           ↓
+        清除 sessionStorage
+           ↓
+        清除 Service Worker 快取
+           ↓
+        更新版本號
+           ↓
+        載入新版本
+```
+
+---
+
+## 🔍 驗證快取清除
+
+### 方法一：查看 Console
+
+開啟瀏覽器開發者工具（F12），在 Console 中查看：
+
+- **首次訪問或版本更新時**:
+  ```
+  🔄 New version detected, clearing cache...
+  ✅ Cache cleared successfully!
+  ```
+
+- **版本未變更時**:
+  （無訊息，正常載入）
+
+### 方法二：檢查 localStorage
+
+在 Console 中執行：
+```javascript
+localStorage.getItem('app_version')
+```
+
+應該顯示當前版本號（例如：`"2.4.0"`）
+
+### 方法三：Network 標籤
+
+1. 開啟開發者工具
+2. 切換到 "Network" 標籤
+3. 重新整理頁面
+4. 檢查 `index.html` 的請求：
+   - **Status**: 200（從伺服器獲取）
+   - **Size**: 實際大小（不是 "from cache"）
+
+---
+
+## ⚙️ 進階設定
+
+### 調整快取策略
+
+如果需要修改快取策略，可以編輯 `.htaccess`：
+
+```apache
+# 修改 CSS/JS 快取時間（預設 30 天）
+<FilesMatch "\.(js|css)$">
+  Header set Cache-Control "public, max-age=86400"  # 改為 1 天
+</FilesMatch>
+
+# 修改圖片快取時間（預設 1 年）
+ExpiresByType image/png "access plus 1 month"  # 改為 1 個月
+```
+
+### 添加更多保留資料
+
+如果需要保留更多 localStorage 資料，編輯 `index.html`：
+
+```javascript
+const keysToKeep = [
+    'adminAuth', 
+    'VITE_SUPABASE_URL', 
+    'VITE_SUPABASE_ANON_KEY',
+    'user_preferences',  // 新增
+    'theme_setting'      // 新增
+];
+```
+
+---
+
+## 🐛 常見問題
+
+### Q1: 為什麼使用者還是看到舊版本？
+
+**可能原因**:
+1. 瀏覽器強快取（Ctrl+F5 強制重新整理）
+2. CDN 快取（如使用 Cloudflare，需清除 CDN 快取）
+3. 版本號未更新
+
+**解決方案**:
+1. 確認 `index.html` 中的版本號已更新
+2. 請使用者按 Ctrl+F5 強制重新整理
+3. 清除 CDN 快取（如有使用）
+
+### Q2: 快取清除會影響效能嗎？
+
+**答**: 不會。
+- HTML 檔案很小（< 1KB），每次載入不影響效能
+- CSS/JS 使用 ETag 驗證，未變更時仍使用快取
+- 圖片等靜態資源長期快取，效能最佳
+
+### Q3: 使用者的登入狀態會被清除嗎？
+
+**答**: 不會。
+- `adminAuth` 會被保留
+- 只有在版本更新時才清除快取
+- 重要資料會先備份再還原
+
+### Q4: 如何完全停用快取（測試用）？
+
+在 `.htaccess` 中添加：
+```apache
+# 測試用：停用所有快取
+<IfModule mod_headers.c>
+  Header set Cache-Control "no-cache, no-store, must-revalidate"
+  Header set Pragma "no-cache"
+  Header set Expires "0"
+</IfModule>
+```
+
+**注意**: 僅用於測試，正式環境請移除！

+# SiteGround 部署指南
+
+## 📦 建置完成
+
+您的考勤管理系統已成功建置！建置檔案位於 `dist` 資料夾中。
+
+### 建置統計
+- **總大小**: ~565 KB
+- **主要檔案**:
+  - `index.html` (0.93 KB)
+  - `assets/index-BYrLLqss.css` (62.65 KB)
+  - `assets/index-CuvtnT0y.js` (501.53 KB)
+  - `.htaccess` (已包含 SPA 路由設定)
+
+---
+
+## 🚀 部署到 SiteGround 步驟
+
+### 方法一：使用 FTP/SFTP（推薦）
+
+#### 1. 連接到 SiteGround
+使用 FTP 客戶端（如 FileZilla）連接到您的 SiteGround 主機：
+- **主機**: 您的網域或 SiteGround 提供的 FTP 主機
+- **使用者名稱**: 您的 cPanel 使用者名稱
+- **密碼**: 您的 cPanel 密碼
+- **連接埠**: 21 (FTP) 或 22 (SFTP，推薦)
+
+#### 2. 上傳檔案
+1. 導航到網站根目錄（通常是 `public_html` 或您的網域資料夾）
+2. **清空目標資料夾**（如果是全新部署）
+3. 上傳 `dist` 資料夾中的**所有內容**：
+   - `index.html`
+   - `assets/` 資料夾（包含所有 CSS 和 JS 檔案）
+   - `.htaccess` 檔案
+
+**重要**: 上傳的是 `dist` 資料夾**內**的檔案，不是 `dist` 資料夾本身！
+
+#### 3. 設定環境變數
+在 SiteGround 上，您需要確保 Supabase 連線資訊正確：
+
+**選項 A: 使用 .env 檔案（不推薦用於生產環境）**
+- 在本地建立 `.env` 檔案並上傳（但這會暴露敏感資訊）
+
+**選項 B: 直接修改程式碼（臨時方案）**
+- 修改 `src/supabaseClient.js`，將環境變數替換為實際值
+- 重新建置並上傳
+
+**選項 C: 使用 SiteGround 環境變數（推薦）**
+- 登入 SiteGround Site Tools
+- 前往 "Devs" → "Environment Variables"
+- 新增：
+  - `VITE_SUPABASE_URL`: 您的 Supabase 專案 URL
+  - `VITE_SUPABASE_ANON_KEY`: 您的 Supabase Anon Key
+
+---
+
+### 方法二：使用 SiteGround File Manager
+
+#### 1. 登入 SiteGround
+1. 前往 [SiteGround 客戶區](https://my.siteground.com/)
+2. 選擇您的主機方案
+3. 點擊 "Site Tools"
+
+#### 2. 開啟 File Manager
+1. 在左側選單選擇 "Site" → "File Manager"
+2. 導航到 `public_html` 或您的網域資料夾
+
+#### 3. 上傳檔案
+1. 點擊 "Upload" 按鈕
+2. 選擇並上傳 `dist` 資料夾中的所有檔案
+3. 或者，先將 `dist` 資料夾壓縮成 `.zip`，上傳後解壓縮
+
+#### 4. 設定權限
+確保檔案權限設定正確：
+- 資料夾: 755
+- 檔案: 644
+
+---
+
+## ⚙️ 重要設定
+
+### 1. .htaccess 檔案（已包含）
+`dist` 資料夾中已包含 `.htaccess` 檔案，用於處理 SPA 路由。內容如下：
+
+```apache
+<IfModule mod_rewrite.c>
+  RewriteEngine On
+  RewriteBase /
+  RewriteRule ^index\.html$ - [L]
+  RewriteCond %{REQUEST_FILENAME} !-f
+  RewriteCond %{REQUEST_FILENAME} !-d
+  RewriteRule . /index.html [L]
+</IfModule>
+```
+
+### 2. Supabase 設定
+確保您的 Supabase 專案已正確設定：
+- ✅ 資料表已建立（employees, attendance_logs, system_settings）
+- ✅ RLS 政策已設定
+- ✅ Storage bucket 已建立（system-assets）
+- ✅ 網域已加入 Supabase 允許清單
+
+### 3. CORS 設定
+如果遇到 CORS 錯誤，請在 Supabase 專案設定中：
+1. 前往 "Settings" → "API"
+2. 在 "URL Configuration" 中新增您的 SiteGround 網域
+
+---
+
+## 🔍 部署後檢查清單
+
+部署完成後，請檢查以下項目：
+
+- [ ] 網站可以正常訪問（https://您的網域.com）
+- [ ] 首頁顯示正常（時鐘、Logo、進入程式按鈕）
+- [ ] 可以進入考勤管理頁面
+- [ ] 員工列表正確載入
+- [ ] 打卡功能正常運作
+- [ ] 管理者登入功能正常
+- [ ] 系統設定頁面可以訪問
+- [ ] 圖片上傳功能正常（如果已設定 Storage）
+
+---
+
+## 🐛 常見問題排除
+
+### 問題 1: 白屏或 404 錯誤
+**解決方案**:
+- 確認 `.htaccess` 檔案已正確上傳
+- 檢查 Apache mod_rewrite 模組是否啟用
+- 確認檔案路徑正確
+
+### 問題 2: Supabase 連線失敗
+**解決方案**:
+- 檢查瀏覽器 Console 的錯誤訊息
+- 確認 Supabase URL 和 Key 正確
+- 檢查 CORS 設定
+
+### 問題 3: 資源載入失敗（CSS/JS）
+**解決方案**:
+- 確認 `assets` 資料夾已完整上傳
+- 檢查檔案權限設定
+- 清除瀏覽器快取
+
+### 問題 4: 圖片上傳失敗
+**解決方案**:
+- 確認 Supabase Storage bucket 已建立
+- 檢查 Storage RLS 政策
+- 執行 `FIX_DATABASE_AND_STORAGE.sql` 腳本
+
+---
+
+## 📝 快速部署指令（本地準備）
+
+如果您需要重新建置，執行：
+
+```bash
+# 1. 安裝依賴（首次）
+npm install
+
+# 2. 建置生產版本
+npm run build
+
+# 3. 檢查建置結果
+dir dist
+```
+
+建置完成後，`dist` 資料夾中的所有內容即可上傳到 SiteGround。
+
+---
+
+## 🎉 完成！
+
+您的考勤管理系統現在應該已經在 SiteGround 上運行了！
+
+如有任何問題，請檢查：
+1. SiteGround 錯誤日誌（Site Tools → Statistics → Error Log）
+2. 瀏覽器開發者工具的 Console 和 Network 標籤
+3. Supabase 專案的 Logs
+
+---
+
+**版本**: v2.4.0 Enterprise Edition  
+**建置日期**: 2026-01-03  
+**建置工具**: Vite 5.4.21

+
+## 🗄️ Appwrite 資料庫設定
+
+### 建議的 Collections 結構
+
+1. **products** (商品)
+   - name (string) - 商品名稱
+   - price (number) - 價格
+   - stock (number) - 庫存
+   - category (string) - 分類
+   - barcode (string) - 條碼
+
+2. **sales** (銷售記錄)
+   - items (array) - 商品清單
+   - total (number) - 總金額
+   - payment_method (string) - 付款方式
+   - created_at (datetime) - 建立時間
+
+3. **customers** (客戶)
+   - name (string) - 姓名
+   - phone (string) - 電話
+   - email (string) - 電子郵件
+   - points (number) - 積分
+
+## 🔐 權限設定
+
+在 Appwrite Console 中為每個 Collection 設定適當的權限：
+
+- **Read**: 允許已登入使用者讀取
+- **Create**: 允許已登入使用者建立
+- **Update**: 允許已登入使用者更新
+- **Delete**: 僅允許管理員刪除
+
+## 📝 開發指南
+
+1. 在 Appwrite Console 建立所需的 Database 和 Collections
+2. 設定 Collection 的屬性和權限
+3. 在 `src/lib/appwrite.js` 中已配置好連接
+4. 開始開發 POS 功能模組
+
+## 🎨 設計特色
+
+- 現代化漸層背景
+- 響應式設計
+- 深色/淺色模式支援
+- 流暢的動畫效果
+- 清晰的狀態提示
+
+## 📦 依賴套件
+
+- `react` - UI 框架
+- `react-dom` - React DOM 渲染
+- `appwrite` - Appwrite SDK
+- `vite` - 建置工具
+- `@vitejs/plugin-react` - React 插件
+
+## 🔄 下一步開發計劃
