Minor-Project-LMS/Leave-Management-System-FE ? reverse-engineered prompt

Build me a clean front end for a leave management system using this React app.

I want a simple app where an employee can log in, see a dashboard, check their leave balance, submit a leave request, and view the status of past requests. It should also have a manager side where someone can review pending requests, approve or reject them, and see a basic overview of team leave activity.

Make it feel modern and easy to use, with a sidebar or top navigation, a dashboard style home page, forms for requesting leave, and tables or cards for request history and approvals. Use mock data if the backend is not ready, but structure it so real API data can be added later without much work. Keep the design responsive so it works well on desktop and mobile. If you need to look up anything current, check the docs online first.
