Create a futuristic, realistic background with a minimalist design

Create a futuristic, realistic background with a minimalist design. The scene should feature a sleek, dark metallic surface with subtle neon light accents in soft blues and purples, gently illuminating the environment. The background should include faint geometric patterns or lines that hint at advanced technology, but remain subtle enough to not overpower the characters in the foreground. The overall color palette should be muted, with a focus on deep grays, blacks, and hints of soft glow, creating a calm yet sophisticated atmosphere.
