2x2 Grid Retro Diner Photoshoot Prompt

A structured prompt for generating a 2x2 grid of photorealistic images featuring the same character (based on a reference image) in a retro 50s American Diner setting. The prompt specifies a 'flash pop color' style, detailed subject appearance (pigtails, ringer tee, milkshake prop), and four distinct poses/expressions (sipping aggressively, seductive cherry bite, bored waiting, goofy laughing).
