Problem
The separate agent and human avatars in the chat header do not clearly communicate how many members are in the conversation or where to manage them.
Proposed design
- Group the existing avatars, member count, and chevron inside one softly rounded neutral box.
- Overlap the human and agent avatars with a clean crossing arc, without white halos or full-circle outlines. Preserve the existing Corbit and human avatar identities.
- Open a compact popover headed Members, with a human/agent count, member names, secondary labels such as You and Agent, and relevant per-member actions.
- End with a single Add member button using the existing brand-orange token, matching
#E98428.
- Keep bench settings separate. Limit the change to this header control and popover.
