+/// Marker trait for types that support structured output (JSON / YAML / TOML / RON).
+///
+/// This trait is a **supertrait** of `serde::Serialize` and is sealed via
+/// `__private::StructuralDataSealed`. It can only be implemented through:
+///
+/// - `#[derive(StructuralData)]`
+/// - `pack_structural!`
+/// - `group_structural!`
+///
+/// These entry points also register the type in the global `STRUCTURED_TYPES`
+/// registry, which is required for the `structural_render` match arm to be generated.
