    "BACKGROUND + PLATE: stays in the brand palette — dark forest green #1f4b37 plate rim, beige #e8e4d8 table surface, sage green #4a7c4e accents. "
    "FOOD COLORS: use realistic but flat-illustrated food tones — "

    "All shapes stay simple, geometric, flat — like cut paper. No textures, no glossy highlights, no shadows under food. "
    "COMPOSITION: a single round plate or bowl centered, viewed top-down or slightly tilted, filling about 75% of the square frame. "
    "FORBIDDEN: text, letters, numbers, watermarks, logos, borders, frames, photo-realistic lighting, lens-flare, "

Fresh sage-green chive bits sprinkled on top. NO green egg.",
