Brand personality must propagate across media

One personality contract drives words, shapes, color, imagery, motion, and constraints.

Ship a cross-medium brand contract before generating marketing or product UI. Do not invent personality mid-component.

Verification contract

Brand modules present; agent skill routes to contract first
