1//! Concrete Syntax Tree (placeholder for future expansion)
2//! The dual-syntax round-trip (C-022) is implemented without a CST: the IR
3//! carries source spans for every node plus comment trivia with normative
4//! attachments, which is enough to re-emit either canonical style. The
5//! parser builds the IR directly.
6//! The alpha parser currently builds the IR directly.
