+//! `youtube-feeder` — a single-upstream feeder sidecar.
+//!
+//! YouTube references as a delegated-playback tier: playback happens on YouTube, no bytes are ever transported or seeded.
+//!
+//! Upstream: YouTube via Piped instances
+//!
+//! Env:
+//! - `META_FEEDER_HTTP_LISTEN` — listen addr (default `0.0.0.0:8080`)
+//! - `META_FEEDER_STATE_DIR`   — per-plugin cache root (default `/data/meta-feeder`)
+//! - `RUST_LOG`                — tracing filter (default `info`)
