//! Core infrastructure: Newton solver, circuit graph, signal buffers.

//! - [`NewtonSolver`] -- generic Newton-Raphson with voltage clamping and step limiting
//! - [`circuit_graph::CircuitGraph`] -- directed processing graph with topological sort
//! and zero-delay-feedback cluster detection
//! - [`node::SignalBuffer`] -- preallocated aligned audio buffers
//! - [`buffer_pool::BufferPool`] -- allocation-free buffer management
/// Allocation-free pool of [`node::SignalBuffer`]s.
/// Processing graph with topological sort and ZDF cluster detection.
/// Fixed-capacity, cache-aligned signal buffers ([`node::SignalBuffer`]).
/// Generic Newton-Raphson solver ([`solver::NewtonSolver`]).
