Describe your issue

I’m getting a typescript error Type '({ opacityVariable, opacityValue, }: { opacityVariable?: string; opacityValue?: string; }) => string' is not assignable to type 'string | RecursiveKeyValuePair<string, string>’ when following this example: https://github.com/adamwathan/tailwind-css-variable-text-opacity-demo.

The example works, and I can see it is calling this as a function, but it doesn’t look like the typing supports it in tailwind.config.ts using import type { Config } from ‘tailwindcss’.
