Summary
Overview is the first signed-in screen: cash, pots, budgets, recent activity, and repeating bills in one workspace.
Result
A first-use account is seeded with the challenge data so the full interface can be evaluated immediately. Later changes belong only to that account.
Lesson
A monthly product needs one home for the loop, not five orphan screens.
