What is the Vercel "framework preset" for Tanstack Start?

I am porting a Next.js app to Tanstack Start. I am still in a feature branch. I have removed all Next.js stuff, but Vercel still say it autodetected a Next.js app. I have also redeployed without the build cache.

The settings also still say Next.js. So I figured I could just manually flip it over to Vinxi, but it's not an option in the list.
