/* ============================================================
   程度測驗（class 前綴 pt-）
   ------------------------------------------------------------
   設計語彙沿用模擬測驗（lt-）：淡底、白色卡片、10px 圓角、按鈕與輸入框 7px、
   標籤 999px，卡片只有邊框不加陰影。色碼一律使用 article.css 的 --article-* 變數
   （各頁一併載入 article.css，故不需重複宣告）。
   刻意不載入 level-test.css，兩個功能的樣式才不會互相牽動。

   響應式斷點：
     1100px 以下  兩欄改為單欄
      768px 以下  統計格線與圖表改為較窄的格線
      560px 以下  全部單欄、作答列改為兩列
