addNode

Appends a custom PdfNode to this container's child list.

Reserved for integration modules that define their own node shapes — for example :pdfkmp-compose-resources enqueues a com.conamobile.pdfkmp.node.LazyNode through this hook so the core DSL doesn't have to know about Compose Multiplatform Resources. End-user code never needs to call this directly; use text, column, row, image, vector, etc.
