//! Crate `zerodds-lang-cst`. Safety classification: **SAFE**.
//!
//! Concrete syntax trees for the seventeen target languages. Built,
//! never parsed.
//!
//! Each language gets the tree its own syntax needs. There is no shared
//! target model: with one, the language-specific part does not
//! disappear, it moves into the renderer, which is where it stops being
//! reviewable.
//!
//! ## Spec
//!
//! - `docs/specs/zerodds-lang-cst-1.0.md` §1.
//!
//! ## Layer position
//!
//! Layer 0 of the backend arc. Depends on nothing — not even on the
//! common AST, so that a tree can be built and rendered without a model
//! and a renderer cannot reach back into one.
