vol9/places-explorer-mern ? reverse-engineered prompt

Build me a full stack travel journal app where I can save places I want to visit or have been to, then browse them in a clean searchable interface.

I want each destination to show useful details, and if possible pull in extra info from Wikipedia so the place pages feel richer without me having to type everything myself. The app should let me add, edit, and remove places, and filter the list in real time so I can quickly find destinations by name, country, or any other useful tag you think fits.

Please make it feel polished and modern, with reusable UI components and a simple experience that works well on desktop and mobile. I want the frontend and backend wired together so it actually saves data and updates smoothly. If you need to look up current docs or best practices for anything, go ahead and do that.
