Redesign the 'GA' monogram into a more graphic, complex, and sophisticated symbol, as if created by a top-tier designer. Move away from standard fonts and create a custom, abstract mark where the letters G and A are artfully and cleverly integrated. The interaction between the letters should be seamless, perhaps using shared strokes or negative space. The final design must be extremely clean, balanced, and geometric, with perfect curves and sharp angles, reflecting a luxurious and premium aesthetic. Black symbol on a solid white background. Flat vector illustration. Remove the tagline.
