+// The Kotlin/Java bindings expose plugin bridges for IPostProcessor,
+// IValidator, IOcrBackend, and IEmbeddingBackend. There is no
+// IDocumentExtractor bridge — extractor selection happens entirely in the
+// Rust core based on MIME type. From Kotlin, the "extractor plugin" pattern
+// is to wrap Kreuzberg.extractBytes / extractFile and dispatch to the right
+// extractor by MIME.
