//! Procedural macro DSL for building OpenInfer graphs.
//!
//! The `graph!` macro parses a compact DSL into `openinfer::Graph` structures.
//! It is intended for ergonomics in tests and examples.
//!
//! ## DSL structure
//! - Memory sections: `dynamic`, `volatile`, `constant`, `persistent`
//! - Blocks: `block entry { ... }`
//! - Nodes: `assign`, `op`, `branch`, `loop`, `yield`, `await`, cache ops
//!
//! ## Expansion
//! The macro expands into Rust code that constructs `Graph` values at runtime.
//!
//! ## Example
//! ```ignore
//! use openinfer::graph;
//! let g = graph! {
//!     dynamic { x: f32[B]; }
//!     block entry {
//!         return;
//!     }
//! };
//! ```
