// Serverless target in Next.js does work if you try to read in files at runtime
// that are not JavaScript or JSON (e.g. CSS files).
// https://github.com/iaincollins/next-auth/issues/281
//
// To work around this issue, this script is a manual step that wraps CSS in a
// JavaScript file that has the compiled CSS embedded in it, and exports only
// a function that returns the CSS as a string.
