An activity's assignees as one overlapping cluster. AvatarStack renders later children on top and drops from the front, so members collapse first while roles and glyph faces, rendered after them, stay visible on overflow.
AvatarStack
Optional
Icon faces for assignee values that are not a person or a role — each icon holds an avatar-sized slot so it stacks with the cluster like any face.
