Paths become surfaces.

The official shapes study builds native Shape paths, converts them through ShapeGeometry and ExtrudeGeometry, and samples paths into Line and Points. This lab makes those construction boundaries and rebuild costs observable.

The official California/11-shape catalog, UV-grid texture, exact camera/pointer/Stats presentation, line/point pairing, and page/pixel fidelity are not copied. Native device/compiler/backend coverage, context-loss stress, and whole-example fidelity remain separate boundaries.
