What issue are you seeing?

The Codex image viewer shows a UI layout bug: the top-right floating controls overlap / crowd together.

In the attached screenshot, the download button and close button are displayed as large circular floating buttons, but their icons/positions appear visually broken or too close together. The close icon also appears duplicated / misaligned.

Screenshot

Attached screenshot shows the issue.

Steps to reproduce

1. Open Codex on Windows.
2. Open a local project / web preview.
3. View an image or screenshot inside Codex.
4. Look at the top-right image viewer controls.

Expected behavior

The image viewer controls should be aligned cleanly, with proper spacing and no overlap.

Actual behavior

The top-right floating buttons overlap / render incorrectly, making the image viewer UI look broken.

What steps can reproduce the bug?

预览随便一个图片都会出现ui显示bug

What is the expected behavior?

希望修复，因为图片预览的x和codex的x重叠了，关闭图片有可能会直接把codex关闭
