AvatarPresence had position:absolute via UserAvatarContainer, which made it position relative to the AvatarDecoration wrapper (a new stacking context) instead of the hero container, shifting the decoration image one avatar-width to the left. Fix: apply UserAvatarContainer to an outer div so AvatarDecoration sits inside the absolute-positioned slot, not the other way around. Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>
