Mental Model
A compressed model based on what we think we know about a system and how it works.
The design-system take
Where the principle shows up in a token, component or pattern decision.
Interfaces that match the model — a trash icon deletes, a gear opens settings — need no manual; mismatches produce support tickets. Novel interactions earn their learning cost only when the payoff is large.
