AI Headshot App Store Promo Poster

Prompt

Create a polished App Store promotional poster for an AI headshot app called {argument name="app name" default="Shine"}, in a warm minimalist brand style. Use a vertical smartphone screenshot ad layout on a soft beige background with a curved golden-yellow shape rising from the bottom edge. Place a large elegant black serif headline in the upper left, split across 3 lines, reading {argument name="headline text" default="Create pro headshots with Shine"}. Add a white jagged starburst badge to the left-center with black serif text reading {argument name="badge text" default="Before + After"}. On the right side, show a large angled modern smartphone mockup, slightly tilted left, with thin metallic edges and a realistic screen.
