Material specifies six springs — three paces × two property families. Each resolves to a physics pair for JS animation and a CSS easing-plus-duration adapter. Why springs at all, and how the two token families relate, is the spring physics guide.
Change the scheme or fork a spring in Customize and watch the values move.
A curve drawn in the tertiary colour crosses above 1 — that is the overshoot. It should only ever appear in the spatial block.
