Field note
Good interfaces leave room for the next decision.
Hierarchy is not decoration. It is how an interface helps someone know what matters now.
Give attention somewhere to land
When every element asks for attention, users have to build their own map. Clear hierarchy makes the next action obvious through spacing, contrast, and deliberate restraint.
Design for the decision
Start with the question a person needs to answer. Then make the information needed for that decision easy to find, compare, and trust.
