Create a cover for an Instagram carousel post with a 1080x1350 resolution (3:4 aspect ratio). Use the first image (the one with abstract blue and white shapes) as the full background. Place the second image (the 'mactub kids baby shop' logo) at the bottom center of the composition. At the top, add the large headline 'МЕМЫ ДЛЯ МАМ' in all caps. Below the headline, add the subheading 'которые хоть раз заходили в mactub.kids 🤍'. The text should be dark grey or black for readability. The overall style should be clean, minimalistic, and professional, matching the provided brand assets.
