Your question is Design Accessible Mobile Feature First. 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).
You're working on a mobile product and the team wants accessibility built in from the beginning instead of added later. You need to think through who may be excluded, which use cases matter most, and how to shape the first version.
How would you design a mobile feature to be fully accessible from the start?
