Refine the golden coffee bean to be even more detailed and realistic, maintaining a clean, minimalist, luxurious style. Add the text 'Nova Coffee' with a subtle, fine, elegant touch, not engraved or burned deeply, and do not split the bean. Place the text gently in the lower right area of the bean, visible but discreet, enhancing the premium feel. Retain the soft swirling mist and the black background with a soft golden glow in the corners, transparent edges, highest resolution.3D illustration
