 *  - Specialist path (`agentId` or `agentNamedId` is a non-empty string):
 *    visible text is the supplied `agentName`, omitted entirely if absent (no
 *    "Rovo" text next to a specialist avatar). Accessible label falls back to
 *    the UUID id, then named id, so the avatar is never announced as "Rovo".
 *  - Default Rovo path (no `agentId` or `agentNamedId`): visible and accessible
 *    labels are the localized default name (typically "Rovo").
 *  - Forge identity props are gated internally via `rovo_agent_support_a2a_avatar`
 *    so callers don't have to.
