Your question is Detailed Design Process. 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 design process in detail. Focus on how you frame the problem, gather input, explore options, make trade-offs, and hand off work for implementation. Include how you handle stakeholder feedback, constraints, and iteration.
