Create a unique emoji-style logo representing 'Harmony UI,' a UI component library for the Symfony ecosystem. The logo should feature a modern, minimalistic design with smooth gradients and a harmonious color palette. Incorporate subtle references to UI elements (such as buttons, sliders, or cards) while maintaining a sleek, professional look. The emoji should feel friendly yet sophisticated, symbolizing ease of use and seamless integration. Consider Symfony’s branding (black and white with elegant curves) but with a fresh, visually appealing twist.emoji
