Referencing TailwindCSS config from JavaScript in SvelteKit

I’m using SvelteKit, which uses Vite and the setup instructions calls for CommonJS config files:
https://tailwindcss.com/docs/guides/sveltekit

However, the guide for referencing the configuration in JavaScript requires ESM.
https://tailwindcss.com/docs/configuration#referencing-in-java-script

Attempting to change the tailwind.config.cjs to ESM doesn’t work (I get errors from other libraries trying to require() it as CJS).

Does anyone know how I can either get a working ESM tailwind.config.js in SvelteKit or a different better method to reference the tailwind config?
