Create a premium advertising cover for an Avito listing. Use the four provided photographs, preserving them exactly as they are without any alterations to the child's face, pose, clothing, lighting, colors, or background. Arrange the four photos into a perfectly symmetrical 2x2 grid with equal spacing and generous white margins on a pure white background (#FFFFFF). Add very soft, natural shadows beneath each photo for subtle depth. The overall design must be a clean, elegant, emotional, modern, and luxurious premium photography studio advertisement. At the top center, add a large bold headline in Russian: 'ВОЛШЕБНЫЕ ФОТОГРАФИИ ВАШЕГО РЕБЁНКА'. Directly under it, add smaller elegant Russian text: 'По обычным фотографиям — без фотостудии и долгих съёмок'. Below the image grid, include four checkmarks with the following Russian text: '✓ Любые локации', '✓ Любые времена года', '✓ Максимальное сходство', '✓ Готово за 1–2 дня'. Use clean, modern, minimalistic sans-serif typography similar to Apple's advertising, with plenty of white space. Do not add any extra decorative elements like flowers, toys, gradients, or stickers. The final image should be print-quality, ultra-sharp, with an elegant editorial design in 8K resolution.
