<https://s.mj.run/hVLGRdnStbU> Analyze the attached app layout and redesign it in a sleek, modern style while keeping the 3x3 button grid structure. Use the same layout but with more refined and polished button designs, clean lines, and a minimalist approach. The primary color should be a rich teal green (#006450) and the secondary color a soft pastel aqua (#bbd8d2). The background and spaces outside the buttons should be pure white with no shadows. Keep the design professional, user-friendly, and suitable for a Power Apps interface. Focus on clean aesthetics, simplicity, and modern UI trends  --s 800
