Questions about the Alert octagon icon
›Can I pause the Alert octagon loop?
It pauses by itself while scrolled out of view and stays on its first frame when reduced motion is preferred or autoplay={false} is set. To show it only while something is pending, render it conditionally.
›Is Alert octagon decorative?
By default it is aria-hidden. Pass aria-label="Alert octagon" to announce it as an image, or leave it hidden when the link or button it sits in has its own text.
›Can Alert octagon loop only while hovered instead?
Yes: pass interaction="hover-loop". It then loops while hovered, finishes the current cycle after mouseleave and stays static when reduced motion is preferred.
