This is only tangentially related but it seems that many of the shapes are built in some sort of 3d program and then exported to svg. If you inspect the official released svgs you can see tons of artifacts in most of the shapes[1]. You would think that Amazon would have the resources to release very optimized icons for its public facing documentation.
