Object-Oriented Programming icon in a blue monochrome palette. Central, stylized class diagram card with three compartments—class name, attributes, and methods—linked by arrows to surrounding blue modules. Cohesive composition with layered depth: foreground class card in sharp focus, midground connections, far background abstract circuitry rendered in softened blue gradients. Cinematic lighting from the top-left creates directional highlights and a cool rim glow along edges, with subtle drop shadows to emphasize form. Textures and details: crisp linework, smooth gradients, glassy reflections, and tactile blue textures. All elements rendered in blues only, no black, for a modern, premium app-icon aesthetic. High-resolution vector rendering with ultra-crisp edges and scalable details.

The image shows a blue flowchart on a blue background with a circuit board in the background. The flowchart is in the center of the image and is composed of several boxes connected by arrows. The blue background provides a vivid contrast to the white box, making it stand out.
