run v4 upgrade codemod on a single file

[bugzpodder]

I've already done a v4 upgrade but since then a bunch of new v3 files were introduced. I am trying to find a way to run the codemod on these new files without success.

I've gotten the upgrade script to run by manually changing the version of tailwindcss to v3, but still don't see my new (tsx) files being updated.

npx @tailwindcss/upgrade --force
≈ tailwindcss v4.0.9

Are the files template files? Perhaps they don't need any changes? Otherwise, you could create a temporary dummy v3 project with the files, invoke the upgrade and then copy the changed files back.
