Kintsugi is the Japanese art of mending broken vessels with lacquer dusted in gold, refusing to hide the fracture and instead tracing it in light. The ground is urushi — sap of the lacquer tree, layered and polished to a deep chestnut black, with the final coat beneath the gold laid in iron-red so the seams sing. This system carries that craft into the interface: dark, glossy lacquer surfaces veined with hand-laid gold, asymmetric and breathing, every edge a repair worth showing.
