A minimalist flat SVG logo design featuring the letters "C" and "O" interconnected. Pure geometric shapes, clean vector paths. The letter "C" forms a bold, solid semi-circle, and the letter "O" is a perfect geometric circle nested within, representing a digital node. Modern corporate tech identity. Solid colors only: deep navy blue and bright electric cyan. No gradients, no shadows, no 3D effects, perfectly symmetrical, transparent background.
