10Planet’s visual system was engineered more like a protocol than a brand. The identity had to signal intelligence, precision, and modularity, without ever drawing attention away from the logic of the system itself. I built a flexible UI grammar from first principles: schema-driven layouts, atomic components, syntax-like accents, and programmable visual density. It was greyscale by default, with highlight rules derived from context, not decoration. The result was a design language that could scale with the protocol, not just style it.
