@import url("https://rsms.me/inter/inter.css");

Notes

Currently, there is an issue with vite-plugin-node-polyfills (0.15.0 at the time of writing), which shows many warnings while building (related to "use client"). That is expected and will probably be fixed in the future. See here: https://github.com/davidmyersdev/vite-plugin-node-polyfills/issues/49
