Clean up the portrait of the middle-aged man with gray hair and a gray mustache, wearing a light collared shirt, against the glowing bokeh light background. Completely remove all watermark text ('макет') and the overlay grid lines covering the image. Restore the clean, clear, crisp texture of his face, hair, mustache, clothing, and the background lights seamlessly without any traces of watermarks or artifacts. Maintain exact facial features, likeness, lighting, colors, and overall portrait composition.
