//! `usenet-feeder` — single-source Usenet feeder sidecar over our own nntmux
//! indexer (the NNTmux app), reached over its Newznab API.
//!
//! One plugin (`usenet`) served through [`meta_feeder_sdk::serve_feeders`].
//!
//! Operator config — the nntmux base URL and API key, and the
//! per-host Newznab indexer keys used to redeem `nzb-release` locators — is read
//! from the persisted `config.json` (dashboard-written), with the env vars below
//! as a **first-boot seed only**: the file wins on the next restart, and there
//! is no hot reload (gateway invariant 12). Indexer keys have no env seed; set
//! them on the config page.
//!
//! Env (seed): `NNTMUX_URL` (default `http://nntmux`), `NNTMUX_API_KEY`.
//! Env (infra): `META_FEEDER_HTTP_LISTEN` (default `0.0.0.0:8080`),
//! `META_FEEDER_STATE_DIR` (default `/data/meta-feeder`), `RUST_LOG`.
