Prototype validation and proof

Problem

The prototype implementation produced SVG chart output, but there was no systematic validation that the default styling, axis behavior, color palette, and typography choices actually looked correct or matched the intended visual language. Without concrete proof artifacts (rendered screenshots, comparison baselines) and repeatable validation steps, it was impossible to distinguish "it runs" from "it renders well." Unvalidated defaults risk shipping charts that technically work but look generic or broken, undermining the differentiation promise.
