PrimitiveFunctionBackedNode

A node backed by a primitive function: the node is wrapped into a call to that function, so any .extend registered for the function name is applied to the node's rendering.

For example, a Heading is backed by .heading, so wrapping .extend {heading} affects both .heading {...} calls and Markdown # syntax. See stdlib's Primitives module for more primitive functions.

The wrapped call carries the original node as its delegator, allowing the expander to skip the function-call machinery entirely when no extension is registered for the backing function.
