Your question is Frontend Performance vs Data Complexity. Take a moment with it on the right.
Talk me through your thinking if you like. When you're confident, submit your answer and I'll grade it like a real screen (7/10 or better passes).
Explain your approach to balancing frontend performance with complex data requirements when building Zipline's UI.
Discuss how you would structure data fetching, caching, state updates, rendering, and loading behavior so complex screens remain responsive without sacrificing correctness. Include the trade-offs you would evaluate and how you would measure whether the approach works.
Keep the answer focused on frontend architecture and runtime behavior rather than visual design or backend implementation.
