//! Contract tests for server install-time operational defaults.
//!
//! Scope: statically guard the generated `/etc/lesavka/server.env` values.
//! Targets: `scripts/install/server.sh`.
//! Why: HDMI capture adapter settings should be reproducible after reboot or
//! reinstall instead of living as one-off shell state.
