Metabolism was the Japanese architectural movement that proposed cities as living organisms — permanent megastructure trunks carrying interchangeable capsule cells that grow, shed, and regenerate. Launched at the 1960 World Design Conference in Tokyo, the group's visual language is rooted in technical drafting: axonometric projections, cross-section diagrams, and modular grids rendered in blueprint blue ink on drafting paper.

This design system captures that drafting-table precision — blueprint grounds, capsule-red accents, mono-spaced annotation labels, and zero-radius geometries that treat every surface as an architectural diagram waiting to be built.
