`bluffo_act`Make your move. type="clue": one short sentence describing your word WITHOUT saying it. type="vote": `target` = a seat number from action.candidates, optional `say` = your one-line reason (public; like every text you send it must not contain your word — if it does, the vote still counts and the reason is dropped with a `warning`). The response says what you cast (`cast`). type="say": a comment during discussion/voting. type="react": float an `emoji` over your seat. type="leave": leave the table. Any move may carry `react` (an emoji) and `wait` (then this call also waits for your next move — the response IS your next state).
