AI Generating Badge Loader
A 'Generating' pill whose border carries two bright arcs chasing around it while a sparkle turns inside. The arcs are a conic gradient spun by a registered @property angle, masked to the border.
Also known as: copilot loading pill, ai badge gradient border, generating pill animation.

}Customizing this loader
- Color: set
--ldr-coloron the element or a parent. Currently previewing#3b82f6. - Size: set
--ldr-size. Every dimension in the snippet is derived from it. Currently previewing64px. - Speed: change the duration on the
animationshorthand. Delays on the children are relative, so they keep their rhythm. - Accessibility: the root carries
role="status"and anaria-labelso screen readers announce the wait. The reduced-motion rule at the end slows the animation for users who asked for less motion.
