A motion token is a design decision with a clock on it

Ask a team how long their transitions run and you'll hear a dozen different numbers. That's the same problem as having a dozen greys.

Start with four

Most products need four durations and two curves. We name them after what they do, like enter, exit, shift and settle, rather than how long they take.

Give the brand a move

Pick one signature motion and use it everywhere: the logo, the page change, the button. Repetition is what people remember, far more than any single animation.

Ship it as code

A token in a PDF is a suggestion. A token in the codebase is the default, and that’s the version engineers actually use.
