Harsha-19/Type-Master ? reverse-engineered prompt

Build me a typing practice app called Type Master.

I want a clean web app where someone can open a page, start a typing test, and see their speed, accuracy, and mistakes as they type. It should have a simple, modern interface that feels easy to use for beginners and people practicing every day. Include a few practice text options, a restart button, and a results screen that shows how well they did after each test.

If it makes sense, set it up with a separate frontend and backend so the app can save test results or user progress later. Keep the design responsive so it works well on desktop and mobile. Please make it polished, working end to end, and easy to run locally.

If you need to check current best practices or docs online while building it, go ahead.
