JRearte/Digesto ? reverse-engineered prompt

Build me a simple digital digest web app for a group project, with a clean front end and a small backend so people can browse content, open an item to see more details, and add or edit entries in a basic way.

I want it to feel modern and easy to use, with a simple layout, clear navigation, and responsive design so it works on desktop and mobile. Keep the flow straightforward, the main goal is to present information clearly and let users manage it without confusion.

Use the existing project structure and TypeScript, and make the app run smoothly from the current frontend and backend folders. If you need to, look up current docs online for any setup details. Keep the implementation practical and finish with everything wired up so I can run it and test it right away.
