lesterwayne11/esimonboard ? reverse-engineered prompt

Build me a working TypeScript app for eSIM onboarding, something simple and clean that lets a user go through the basic setup flow and see that it works end to end.

I want the project to run without errors, have the main screens or logic wired up, and include whatever placeholder data or mock flow is needed so I can test it right away. If anything is unclear, make reasonable choices and keep it straightforward. Use the existing project setup in this repo, and look up current docs online if you need to.
