//! Cross-file / project-level analysis.
//!
//! Where the parser and (future) per-file semantic layer are strictly
//! single-file, this module models how files relate: the `\input`/`\include`/
//! `\import` inclusion graph. Extraction is **purely syntactic** — it reads the
//! generic CST with small local helpers and needs no signature DB or semantic
//! model — so it lands ahead of those Phase 3 items (AGENTS.md decision #2:
//! meaning never leaks into the syntactic layer).
//!
//! This is the LaTeX analog of arity's `project/` module; the file shapes track
//! arity's (`source.rs` ↔ `include.rs`, `scope.rs`/`graph.rs` ↔ `graph.rs`) so a
//! later shared-crate extraction stays a mechanical lift.
