rancher/dashboard ? reverse-engineered prompt

Build me a polished web dashboard for managing Kubernetes clusters and workloads, like the Rancher UI.

I want a clean home screen, a way to see clusters at a glance, drill into workloads, and manage the most important things an admin would need day to day. It should feel like a real production console, with good navigation, search, tables, detail pages, and clear status indicators. Please also leave room for extensions so extra features can be added later without redesigning the whole app.

Make it responsive, modern, and easy to use, and use current best practices for the framework and tools in this repo. If you need to check up to date docs or patterns while building it, go ahead and look them up online.
