I noticed a potential UI bug on Vercel's domain checkout page.

When trying to purchase a domain using a desktop-sized browser window, the "Buy" button was not visible on the checkout page.

However, after resizing the browser window to mobile dimensions, the button suddenly appeared.

It seems like there might be a responsive layout issue causing the purchase button to be hidden or improperly positioned on larger screens.

Steps to reproduce:

Go to Vercel's domain purchase/checkout page.

Use a desktop-sized browser window.

Notice that the "Buy" button is missing.

Resize the browser window to mobile dimensions.

The "Buy" button becomes visible.
