//! Binary entry point: prints a hello message.
//!
//! The actual binary targets live under `src/bin/` (gated on the
//! relevant feature flags). `src/main.rs` is a stub kept so the
//! crate can be invoked as `cargo run --bin tokitai-operator` and
//! produce a friendly hello message. All real entry points are
//! the `[[bin]]` targets in `Cargo.toml` and the
//! `cargo run --example ...` targets in `examples/`.
