This is a spec: descriptive guidance, not a checkable rule. It carries no forbidden and instead pair, and no jig check detector applies to it directly.
The spec
When density and legibility conflict, decide by the user's real conditions, not by preference.
A first-time visitor on mobile data in bright sun and an operator at a large display for eight hours need opposite things. Mode encodes this. When the mode is genuinely unclear, ask — do not average, because the average serves neither.
