For Hero: like `icon`, but a larger, card-styled profile picture of the resource's own SemanticSvg (rendered at its card tier) beside the title block — a profile-header layout where the title and subtitle sit next to the picture. Use for resources whose SemanticSvg is a portrait (e.g. a Person), where `icon` is for a small identity glyph. When both are set, avatar wins.
