//! Raw bindings for a small C ABI shim over M5Unified.
//!
//! This crate intentionally does not bind M5Unified's C++ classes directly.
//! Instead, `native/m5u_shim.cpp` exposes stable `extern "C"` functions that
//! Rust can call from the higher-level `m5unified` crate. On non-ESP-IDF host
//! targets these functions are stubbed so the safe wrapper and translated
//! samples can be checked in CI without hardware.
//!
//! Firmware projects targeting ESP-IDF must provide the native shim component
//! from this crate's `native/` directory in their ESP-IDF component graph. The
//! host stubs are compile-time conveniences only and do not simulate M5Stack
//! hardware behavior.
