I left some comments for a11y, and I think we'll also need to bump the readme cache key 🙏

❤️ This is such a great little feature! I think all these little delightful touches in the app are how we make npmx shine and be successful!

I wonder if there's any way we could accomplish this with native CSS transitions?

Since this is making leaky assumptions about the DOM structure here, this feature seems like a prime candidate for some test coverage.
🙏🏼 Would you be up for opening a follow-up PR with at least a happy path test? Otherwise we can open an issue to track it.
