Cognitive Load
The amount of mental resources needed to understand and interact with an interface.
The design-system take
Where the principle shows up in a token, component or pattern decision.
Load comes from ambiguity, not length: unclear labels and inconsistent patterns cost more than a long but predictable page. Every decision the interface makes for the user is load removed.
