//! Demonstrate `DepProducer` — the `dev_report::Producer` adapter.
//!
//! Construction is always safe and cheap. The actual subprocess
//! invocation is gated behind the `DEV_DEPS_EXAMPLE_RUN` env var so
//! CI doesn't pay for a full dependency check on every example build.
//!
//! ```text
//! cargo run --example producer
//! DEV_DEPS_EXAMPLE_RUN=1 cargo run --example producer
//! ```
