+//! Partial port of seld/jsonlint.
+//!
+//! The parser, lexer, and duplicate-key exception (`JsonParser`, `Lexer`,
+//! `DuplicateKeyException`) are intentionally not ported: JSON syntax validation now relies on
+//! serde_json, and duplicate-key detection is done with a hand-written serde visitor, so
+//! jsonlint's own parsing machinery is no longer needed.
+//!
+//! `ParsingException` is kept because it is the exception type thrown for invalid JSON and is
+//! matched (via downcast) across the codebase as an error-kind signal; it also carries detail
+//! such as the error line. Porting it keeps both the thrown exception class and the information
+//! it carries unchanged.
