Design a sleek and clean high-tech background that exudes sophistication and minimalism. The backdrop should be predominantly white, accented with very light shades of blue and gray. Incorporate sparse, thin lines that suggest connectivity and technology, and add a few abstract, geometric shapes that are futuristic yet subtle. The shapes should be semi-transparent, adding to the design without cluttering it. The overall feel of the image should be airy, open, and modern, with a sense of elegance and high-end technology.
