himakshikhangar/student-dashboard ? reverse-engineered prompt

Build me a browser based student dashboard called Campus Desk for college students.

I want it to help manage a busy week in one place, with a home screen that greets the user and shows the most important stuff at a glance, plus sections for timetable, attendance, exams, grades, focus time, notices, and profile settings. It should work without a backend or sign up, and save everything in the browser so it stays after reload.

Make the timetable editable, let attendance be tracked per subject, show exam countdowns, calculate GPA and CGPA from entered marks, and include a Pomodoro style focus timer with a simple task list. Add a small notice board, theme switching between light and dark, and a demo data button so the app can be filled with sample content quickly.

Please make it feel polished and animated, with smooth transitions and a responsive layout, and use browser notifications for class reminders if possible. Look up current docs online if you need to.
