ZyaknOw/internet_cafe ? reverse-engineered prompt

Build me a simple internet cafe management app with a clean frontend and a backend that work together.

I want a web app where I can see the current PCs, whether they are free or in use, start and stop a session, and track basic customer usage time. It should feel easy to use for someone at a front desk, with a clear dashboard, simple forms, and obvious status labels. If it makes sense, include a way to add or edit machines and view recent activity.

Please set up both the frontend and backend so the app runs smoothly end to end, and make the UI look modern but straightforward. Use sensible defaults, handle loading and error states, and make sure the main flows are easy to test. If you need to look up current docs online, go ahead.
