Tree — leaf nodes
=================

**Leaves** are terminal :class:`Node` subclasses: they do not wrap other nodes as children. They are where concrete implicit geometry and sources live—analytic primitives, meshes, CAD imports, lattices, extruded profiles, and signed-distance fields.

Nodes that combine or transform subtrees are **composition** operators; see :doc:`composition`.
