  主視覺的遮罩。

  原則：遮罩是為了「保證文字讀得到」，不是替底圖重新上色。
  所以只在文字所在的位置壓深，四周留給圖片本身，而且一律用中性的深藍
  （--navy），不加飽和的藍或青 —— 底圖是後台可上傳的，任何色調都可能，
  疊一層有顏色的漸層上去只會讓每張圖都變成同一種混濁的紫藍。

  三層由上而下：
    1. 標題在正中央，那一圈壓深確保對比
    2. 頁首的白色選單壓在上緣，需要一條深帶子
    3. 底部收一點，跟下一段內容銜接

 *
 * 純 CSS，不依賴 JS。底圖本來就是立即顯示的 <img>，這裡只是讓文字那塊
 * 淡進來；動畫不跑也不影響內容看得見。
 *
 * 用 backwards 而不是 forwards：backwards 保證動畫開始前元素就是起始狀態
 * （opacity: 0），不會有「先以正常樣式畫一次、再跳回 0 開始淡入」的空窗。
 * forwards 則是留住結束狀態，這裡不需要 —— 結束狀態本來就等於元素的正常
