      "concept": "A two-frame editorial diptych shot from above: a glamorous woman lying on a carpeted floor in a {argument name="dress color" default="deep blue"} satin halter dress. Phone/compact-camera flash aesthetic, candid late-night energy. Frame one is sharp with a relaxed smile and eyes closed; frame two has intentional motion blur from a sudden head turn, creating a chaotic-chic vibe.",
