Build me a simple app called ResearchHub where people can save, organize, and browse research items in one place.

I want a clean modern interface where someone can add a title, short summary, tags, and a link or note for each item, then search and filter everything easily. It should also have a basic dashboard so users can quickly see their saved research at a glance, with the ability to edit and delete entries.

Please make it feel polished and easy to use, with sensible empty states, loading states, and responsive design for mobile and desktop. If you need to look up current docs online to make the setup cleaner, go ahead. Keep the code organized so it would be easy to extend later for things like user accounts or sharing.
