Overhead Superhero Mahjong Scene Prompt (WeChat Moments Style)

A detailed, structured prompt for generating a surreal, ultra-wide overhead flat lay photograph featuring four characters (specifically Marvel superheroes in the example) playing Mahjong on a custom table designed to look like a WeChat Moments post. The prompt meticulously defines the composition, negative space, lighting, and the specific design elements of the table's top and bottom borders to mimic the social media interface.
