Agent Error With Retry
A calm failure card for Build failed with 2 type errors: no shake, just a soft red icon, a ring that drains as Retrying in 3, 2, 1 counts down, then a quiet Retrying spinner. All @property driven.
Also known as: error state animation, retry countdown, ai error message ui.

}Customizing this snippet
- Color: set
--aia-coloron the element or a parent. Currently previewing#3b82f6. - Base size: set
--aia-size. Every other dimension is inem, so the whole thing scales together. Currently previewing16px. - Speed: change the duration on the
transitionoranimationshorthand. Staggered delays are relative, so they keep their rhythm. - Reduced motion: the rule at the end of the CSS turns the motion off for people who asked their OS for less of it. Keep it.
