Brand style: {argument name="brand style" default="[BRAND / PREMIUM / LUXURY / TECH / BEAUTY / FOOD / DRINK]"}
Main subject: {argument name="subject" default="A confident model holding or presenting the product close to the camera, with the product in sharp focus and the model slightly behind it"}. Use a strong perspective angle so the product feels powerful, premium, and hero-like.
