//! Loadback test for `packaging/linux/configs/ws-bridged.yaml.example`.
//!
//! Background: the shipped example yaml historically had a
//! schema (`participant:` / `websocket:` / `routes:` / `observability:`)
//! that the parser silently ignored with `_ => {}`; the bridge
//! booted with defaults instead of the user-configured values (Issue #3
//! on github.com/zero-objects/zero-dds).
//!
//! This test prevents a recurrence: the shipped example
//! YAML is embedded at build time via `include_str!` and run through
//! `DaemonConfig::load_from_str`. If doc drift strikes again in
//! the future, it surfaces here — not only in the field.
//!
//! Spec reference: `docs/specs/zerodds-ws-bridge-1.0.md` §3 (config file format).
