+Week 10 - 魔法手勢：Pinch 偵測與手勢按鈕 (三指捏合挑戰 Template 填空版)
+==================================================================
+本週挑戰目標：
+  1. 實作「三指捏合 (Three-Finger Pinch)」：
+     必須同時滿足「大拇指 (4) 與食指 (8) 的距離 < Threshold」
+     以及「大拇指 (4) 與中指 (12) 的距離 < Threshold」才判定為 Pinch
+  2. 用三指碰觸 Pygame 畫面上的按鈕 + 捏合 = 魔法點擊
+  3. 使用邊緣觸發 (Edge Detection) 防止重複觸發
+  4. 新增 30 秒限時機制，時間到顯示最終得分

+# 歷屆作品展示備忘
+
+此展示學生是歷屆作品的策展入口，收錄多件作品，不代表全部由同一位學生獨立完成。原有作品檔案保持不動。
+
+## 展示順序
+
+1. `01_手勢按鈕挑戰`：MediaPipe 手部追蹤與三指捏合遊戲。
+2. `02_臉部3D網格`：MediaPipe 臉部網格／特徵點視覺化。
+3. `03_手指空中畫畫`：以手指追蹤繪圖。
+4. `04_Fire迷宮`：MakeCode Arcade 外部作品。
+
+## 展示前檢查
+
+- 前三項需要瀏覽器 Webcam。播放器會把鏡頭影格透過 WebSocket 傳到 HF 執行環境處理；請先告知體驗者並取得同意，不要在未告知的情況下讓學生或家長入鏡。
+- 這些作品尚未在目前 HF Space 上逐一完成實機排練。請先檢查鏡頭權限、模型載入、畫面反應及停止後鏡頭是否關閉。
+- `hand_landmarker.task` 與 `face_landmarker.task` 由部署端的共用 `models/` 提供，執行器會連結到專案；若移動或另行打包作品，需一併保留模型來源。
+- MakeCode 作品會在外部 MakeCode Arcade 開啟；操作控制尚未逐項驗證。
+- 本資料夾是原作品的展示副本，沒有改寫原班檔案，也沒有推送部署。
