Overlapping avatars summarizing a group.

Show the markup

<div class="cc-avatar-stack" role="img" aria-label="Approved by Kerri McManus and Thomas Berube">
  <span class="cc-avatar" aria-hidden="true">KM</span>
  <span class="cc-avatar" aria-hidden="true">TB</span>
</div>

Accessibility

The stack is one image to assistive tech: role="img" with a label naming the people (or the count).
Individual avatars inside are hidden from the tree — no initial-soup announcements.
