An edge: a bounded piece of a curve between two vertices.
A handle to a shape living inside the OpenCascade kernel, not the geometry itself. The kernel
runs as WebAssembly with its own memory, so what crosses back into JavaScript is this small
reference; pass it to the next operation to keep building. It cannot be inspected or edited
directly - use the shapes and query APIs for that - and it stays valid until the kernel's cache
is cleared.
