MomoPi-Dark/WEB_MONITORING — reverse-engineered prompt

I want this turned into a simple web monitoring app in the existing Next.js project. The main idea is that I can add a few website URLs and see a clean dashboard showing whether each site is up, how fast it responds, when it was last checked, and a simple history of recent checks.

Please make it feel modern and easy to use, not overly technical. I’d like a homepage dashboard, a way to add and remove monitored sites, and clear status colors for healthy, slow, or down. If it makes sense, include a detail view for each site with recent response times and uptime info. A few example entries are fine if there is no backend yet.

Keep the setup practical so it can run locally without a lot of extra work. If you need to, look up current Next.js docs online and use sensible defaults. I’d also like the app to be responsive and polished enough that it looks like a real monitoring tool, not just a starter template.
