v4 alpha does not work on Stackblitz

Problem

What version of Tailwind CSS are you using? 4.0.0-alpha.6 What build tool (or framework if it abstracts the build tool) are you using? Vite 5.1.5 What version of Node.js are you using? v18.18.0 What browser are you using? Chrome What operating system are you using? StackBlitz Reproduction URL https://stackblitz.com/edit/vitejs-vite-bhcbjy?file=vite.config.js&terminal=dev A Tailwind Play link or public GitHub repo that includes a minimal reproduction of the bug. Please do not link to your actual project, what we need instead is a _minimal_ reproduction in a fresh project without any unnecessary code. This means it doesn't matter if your real project is private/confidential, since we want a link to a separate, isolated reproduction anyways. A reproduction is required when filing an issue — any issue opened without a reproduction will be closed and you'll be asked to create a new issue that includes a reproduction. We're a small team and we can't keep up with the volume of issues we receive if we need to reproduce each issue from scratch ourselves. Describe your issue [code block]
