RARA-star969/No-wait-Salon ? reverse-engineered prompt

Build me a simple no wait salon app for customers and staff.

I want a system where customers can see the salon wait status, join a line or book an appointment, and get updates so they know when it is close to their turn. Staff should have a companion view to manage the queue, check people in, mark services as started or finished, and see who is next. If it makes sense, include a basic admin area for salon settings, hours, and service info.

Make it feel polished and easy to use on mobile first, since there are separate customer and staff apps. Keep the code organized in TypeScript, and wire up the front end, backend, and the main flows so it works end to end. If you need to, look up current docs online for any libraries or setup details.
