"Design a professional and modern logo that replaces the traditional '@' symbol with the letter 'M'. The logo should maintain the recognizable swirl of the '@' symbol, but the central space should be filled with a stylized, sleek 'M' that seamlessly integrates with the swirl. Use a minimalist style with clean lines. The color scheme should be a gradient of blue and green, reflecting a tech-savvy and innovative feel. The logo should be suitable for digital media and print, emphasizing clarity and scalability.
