19/// An original source AST node preserved verbatim for re-emission when the
20/// compiler bails on a construct it does not model (`UnsupportedNode`).
21///
22/// Holding the typed node directly — rather than a `serde_json::Value` — lets
23/// lowering stash it and codegen restore it without round-tripping through
24/// serde, which is what kept the AST (de)serializers out of the generated
25/// binary. The variant records which syntactic position the node came from, so
26/// codegen can dispatch without re-parsing a `type` tag.
