How to set up css/scss global for ionic/[Vue]?

Since the install of ionic/vue doesn’t install the unminified css or anything for that matter in the project /src directory, how can I set the css global variables for an ionic/vue project?

I have loaded them into my App component like this

<style src='@ionic/core/css/core.css'></style>
<style src='@ionic/core/css/ionic.bundle.css'></style>

See project -
