//! Language parser definitions using the `define_parser!` macro.

//! Each parser is generated with a single macro invocation, replacing
//! thousands of lines of copy-paste adapter code.
//!
//! Parsers with incompatible tree-sitter bindings (Dart, SQL, Kotlin)
//! gracefully fail at initialization.
