Motion craft — movement that reads as intent

Motion is not decoration laid over an interface. It is the interface explaining what just happened: what appeared, what it came from, what is still loading, what the user just did. When motion feels wrong the complaint is almost never "the curve is off" — it is "this feels cheap", or "slow", or "I don't know what happened". Those are the symptoms this skill exists to convert into decisions.

The one rule

Every animation answers a question the user is already asking. If you cannot name the question, delete the animation — it is costing time and attention and returning nothing.
