{"A smiling young woman with fair skin and freckles posing in a gym. She is sitting sideways on a workout bench, leaning back with one arm raised behind her head. She wears a fitted brown athletic bodysuit with thin straps and a brown baseball cap with the word '{argument name="cap text" default="SADIE"}' on it. Her expression is relaxed and cheerful, eyes slightly closed. The background shows a dimly lit gym environment with blurred workout equipment. Soft lighting highlights her skin and creates a cinematic, shallow depth-of-field effect.", "style": "写实摄影，电影感灯光，浅景深", "camera": "肖像照，中景特写，略带角度", "environment": "现代室内健身房，模糊背景", "mood": "放松，自信，温暖"}。迭代思路：同一参数下生成 3 次，挑出色彩、姿态最契合品牌调性的版本。
