how can I custom scan-files in v4 with vite?

[yanquer]

I create a private-npm-package and install it in another project, but some tsx-files which in private-npm-package contain tailwind-css-var do not work.

the project which use private-npm-package use tailwind with https://tailwindcss.com/docs/installation/using-vite

how can I custom scan-files in v4 with vite to solve this?
