//! # Axicor Core
//!
//! Shared types, constants, and SoA (Structure of Arrays) memory layout for the Axicor
//! spiking neural network engine. This crate enforces zero-cost C-ABI contracts
//! for cross-platform DMA and GPU execution, strictly avoiding runtime allocations.
//!
//! ## Module Index
//!
//! - `[layout]` GPU-aligned data structures (`BurstHeads8`, `VariantParameters`).
//! - `[ipc]` Cross-platform shared memory and Zero-Copy IPC primitives.
//! - `[physics]` Integer GLIF neuron model and GSOP plasticity math.
//! - `[signal]` Axon propagation math (branchless, zero-float).
