   ========================================
   📍 更换背景图片：将你的图片重命名为 bj.jpg 替换现有文件
   📍 或修改下面的 'bj.jpg' 为你的图片文件名
   📍 显示方式选择：
   - center/cover（推荐）: 居中并覆盖整个区域
   - center/contain: 居中但完整显示图片
   - top/cover: 顶部对齐 | bottom/cover: 底部对齐
   - left/cover: 左对齐 | right/cover: 右对齐

   - 0.05 = 5% 透明（几乎完全透明，背景很清晰）
   - 0.15 = 15% 透明（当前设置，较清晰）
   - 0.25 = 25% 透明（适中）
   - 0.50 = 50% 透明（半透明）
   - 0.80 = 80% 透明（大部分遮挡，背景朦胧）
   📍 建议桌面端范围：0.10-0.20
