Want to get the scss configuration of material design

[bre97-web]

Hello everyone, I would like to ask a question: Where can I get customizable configuration files?

When I read the tokens folder of this project, I noticed that those .scss files all had comments like this:

//
// Copyright 2023 Google LLC
// SPDX-License-Identifier: Apache-2.0
//
//
// !!! THIS FILE WAS AUTOMATICALLY GENERATED !!!
// !!! DO NOT MODIFY IT BY HAND !!!
// Design system display name: Google Material 3
// Design system version: v0.192
// User-configured context group "Audience": "3P"
// User-configured context group "Platform": "Web"
// User-configured context group "Scheme": "Dynamic"
//

If I could get the source I would be grateful.
