Feature Description

What does this add?
This adds the ease-badge-pulse component, which features an infinitely expanding notification alert indicator ring.

How does a developer use it?
Developers attach the core structural class alongside one of the four built-in semantic variant flags:

<span class="ease-badge-pulse badge-danger"></span>

It answers a standard design system pattern for real-time unread messages and online user indicators using zero-JavaScript layout triggers.
