Create a playful 16:9 editorial 3D illustration featuring [Character One] and [Character Two], two original fictional mascot characters or user-owned characters, casually sitting together at a table in a [Restaurant Theme] fast-casual restaurant. The restaurant should feel colorful, friendly, and completely fictional, with no real brand names, no recognizable logos, and no existing copyrighted characters unless the user owns the rights. Show trays of burgers, fries, salad, fruit, and colorful drinks, warm interior lighting, expressive character poses, and a light-hearted conversation mood. Use polished 3D illustration detail, cinematic composition, clean food styling, and reusable GPT Image 2 prompt-template clarity. Avoid watermarks, random logos, real brands, protected characters, readable text, malformed food, extra limbs, and low-resolution artifacts.
