"Design a modern, 16-bit pixel art-inspired landing page for the ‘Healthy Eating Challenge’ app. The page should blend nostalgic pixel aesthetics with sleek, contemporary web design, capturing the essence of a foodtech platform. Incorporate playful, pixelated characters and food items that represent healthy meals, along with retro-style icons for logging meals, group competitions, and AI scoring. The color scheme should be vibrant yet clean, with clear sections highlighting the app’s features like meal reminders, Nutri-Score grading, and group challenges, all while maintaining a user-friendly, engaging experience."
