"Build a complete, responsive Time Tracking App called Trackr. The app should let users track time, manage projects and clients, visualize workload, and generate invoices. Include the following pages: Dashboard, Time Log, New Entry, Clients, Projects, Invoices, and Settings. Add bar and pie charts for tracking time. Use Inter font, white background, and #3C82F6 blue accents. Cards should have soft shadows and rounded corners. Make it fully responsive with sidebar nav on desktop and bottom nav on mobile."
