Restores the Dim (dark blue) background option to X/Twitter display settings.
恢复 X (Twitter) 的“暗淡 (Dim)”模式。
X 官方近期从网页版显示设置中移除了经典的深蓝色“暗淡 (Dim)”背景，只剩下了纯黑（本体）和纯白。如果你觉得纯黑太刺眼、纯白太明亮，这个脚本将为你带回那个深受喜爱的深蓝色中间色调。
Bring back the beloved "Dim" background to X/Twitter.
X recently removed the "Dim" (dark blue) background option from the web display settings, leaving users with only "Default" (white) and "Lights Out" (pure black). This script restores the classic blue-grey aesthetic that many users find much easier on the eyes.
