great create our poc working client package, break the concepts into distinct folders, break the functionality down into granular SRP services any shared functionality between services should be broken out into helpers, make sure the code is SOLID DRY and pure functions, let’s really try to nail the file and folder structure with friendly apparent naming. this is going to be a fairly complex file structure. i want you to think through each process and deeply layer the functionality while also being concious of any chance to reuse or DRY the code into a reusable script. the app should be loosely-coupled, flexible, modular and optimized. the main code focus is on the lip mapping logic. include a package.json and brief README.md. return the entire well-thought out file and folder scaffolding poc as a downloadable zip.
