* @note The block below contains polyfills for Node.js globals
* required for Jest to function when running JSDOM tests.
* These HAVE to be require's and HAVE to be in this exact
* order, since "undici" depends on the "TextEncoder" global API.
*
* Consider migrating to a more modern test runner if
* you don't want to deal with this.
