"Design an abstract background that combines technology-inspired patterns with a coffee color palette. Visualize intricate digital or geometric patterns, resembling circuitry or digital networks, rendered in a range of coffee tones--rich browns, creamy beiges, and soft whites. These patterns should be subtly layered and textured, creating a sense of depth and complexity. The design should evoke a sophisticated tech feel while remaining warm and inviting due to the coffee-inspired hues. Aim for a balanced, harmonious composition that could serve as a stylish yet understated backdrop for digital content."
