DJ-Raven/java-swing-school-management-dashboard — reverse-engineered prompt

Build me a nice looking Java Swing desktop dashboard for a school management system, similar to a modern admin panel. I want it to feel polished visually, with a left side menu, a top area, cards for key school stats, and main content sections that can switch between pages like dashboard, students, teachers, classes, and settings.

It doesn’t need a real database yet. Use sample data so the UI looks complete and useful. Focus on the layout, colors, icons if available, hover effects, and making the interface feel smooth and professional. Include two visual versions if that makes sense, one basic and one more updated looking, since this project seems to show a version 2 design.

Please make it easy to run in a Java IDE, keep the code organized, and add simple comments where helpful. Look up current Java Swing examples or docs online if you need to.
