Preserve the exact bananas, their natural texture, shape, color, and arrangement. Improve the image for a Persian Instagram post in a 4:5 portrait crop. Make the background slightly lighter and more neutral while retaining a warm natural feel. Add a soft realistic grounding shadow beneath the bananas and improve subject-background separation with subtle contrast. Create clean negative space above the product for Persian typography. Add the Persian headline exactly as: «تازه، شیرین، ایرانی» in a bold, highly legible Persian font at the top, with strong contrast and balanced spacing. Do not add logos, extra objects, watermarks, or English text. Keep the result natural, premium, and suitable for Instagram.
