Kartik-pro/Teacher-Helper ? reverse-engineered prompt

Build me a simple teacher helper web app called Learning Hub that helps a teacher keep track of classes, students, assignments, and progress in one place.

I want a clean dashboard where I can quickly see upcoming work, recent activity, and which students need attention. It should let me add classes, create assignments, record grades or notes, and mark tasks as done. Please make it easy to switch between views for overview, students, and assignments, and keep the interface friendly and uncluttered so it feels useful during a busy school day.

Use the screenshots in the repo as the visual reference if they help, and make the app polished and responsive so it works well on desktop and tablet. If anything is unclear, use sensible defaults and look up current docs online if you need to.
