Cast members: the account’s own and the starters

The AI actors and AI influencers the person can put in their work: their own, and the starter cast every account has. Each with its id, name, label (every synthetic person is labelled: "AI actor", or "AI likeness" for a real person's), look, voice and languages, and every picture of theirs — the hero, each page of their sheet, each view — with a link to open or download it. Use an id as a presenter in a UGC ad or an avatar, to animate an influencer, or on a board as a cast card, the starter cast’s as well as their own (POST /api/v1/boards/{boardId}/place, or a cast card in POST /api/v1/boards/{boardId}/cards); a voiceId reads words in their voice (POST /api/v1/voiceovers, or an avatar’s script); for one of their pictures in another create tool, pass {kind: "cast", id} to POST /api/v1/library/use. Free.
