Build me a simple React app for managing a list of items, something like notes, tasks, or contacts, with full create, view, edit, and delete flows.

I want a clean, modern UI that works well in the browser and feels polished, with a form to add new items, a table or card list to show them, and easy inline or modal editing. Please make it responsive and keep the experience straightforward for someone who just wants to add, update, and remove records quickly.

Use the existing React and Vite setup, and if you need any current best practices or docs, look them up online. If there is no backend in place yet, use local state or a simple mock data approach so the app is still fully usable. Keep the code organized and easy to extend later if I connect it to an API.
