Design a minimalistic product ad with a gradient background that transitions from light pinkish-orange (#F3A589) at the top to pale yellowish-orange (#F9D49B) at the bottom. Place a subtle white shadow texture at the bottom. At the top, center the text 'A Chaotic Brain ≠ Productivity' in bold, black sans-serif font, with each phrase inside white rectangular boxes with black borders. The ≠ symbol should be bold and black, centered between the two boxes. Add a small, handwritten-style black logo at the very top-center. Ensure the layout is clean, with the product displayed at the bottom center and a light shadow beneath it for depth."
