brink-syntax-native 0.0.16

//! Lexer and error-resilient CST for the `.brink` native surface.
//!
//! This crate is the **B0.5 grammar skeleton** (`docs/b0-sequencing.md`
//! §B0.5): the token vocabulary and a lossless, error-resilient rowan CST
//! for the ruled native surface subset (`docs/native-surface-charter.md`
//! §5/§6, NF-2's writer-sufficient subset). It performs **no HIR
//! lowering, no resolution, no type-checking** — those are B0.6/B0.7/B0.8.
//!
//! Peer crate to `brink-syntax` (the ink frontend), per the NF-1 ruling: its
//! own `SyntaxKind` space, its own rowan tree, depending on nothing
//! ink-shaped.
