//! GPU DFA lexer pipeline for Rust source text.
//!
//! Reuses `vyre-primitives::text` byte-classifiers and the sparse-dispatch
//! pattern proven in the C11 lexer. The CPU reference (`core::lex`)
//! is validated token-for-token against `rustc_lexer`.
/// Post-lex keyword promotion.
/// Lexer kernels (CPU reference + GPU plan builder).
/// Token constants and predicates.
