Use Animated Bounds Sparingly

Animated bounds is a subtle effect. Use it for buttons, accordions, and interactive elements — not everywhere.

Good use cases: loading state buttons, expandable sections, accordions, FAQs, content reveals.

Bad use cases: every container on the page, static layouts, elements that don't change size.
