Grows slightly on hover and squishes down on press, with an overshooting easing curve so it feels springy rather than mechanical. Great for playful products and games.
Also known as: bouncy button, spring scale hover.

Currently previewing #3b82f6.--hfx-size. Every other dimension is in
em, so the whole thing scales together. Currently previewing 16px.transition or animation
shorthand. Staggered delays are relative, so they keep their rhythm.
