         <div class="bg-veil"></div>    ← 极淡纸色蒙版（只为压对比度）
   去掉 body 上的 bg-photo 即恢复纯纸色背景。
   --------------------------------------------------------------------------
   关键点：
     1. .bg-fixed 用 position:fixed —— 不随页面滚动，一直看得见壁纸
     2. 壁纸本身已预先抬亮 + 轻微柔化（desktop-bg-fixed.jpg），
        所以蒙版可以做得很淡，不会遮掉画面
     3. .bg-veil 也是 fixed —— 蒙版不随滚动漂移，全页对比度一致
