//! [`EffectLogger`] as a service value: each method returns an
//! `Effect<(), EffectLoggerError, R>` that is run with [`effectful::run_blocking`]
//! against a `()` environment (the logger is self-contained after extraction).
//!
//! Run: `RUST_LOG=debug devenv shell -- cargo run -p logger --example effect_logger`
