/**
 * Runtime override tests -- MEDIUM tier.
 *
 * Live view, MQTT, and Home Assistant toggles change a camera's running config
 * without touching yaml, and the change persists across restarts. The settings
 * form edits yaml, so it keeps showing the saved value. Without a marker on the
 * field and runtime-aware wording on dependent warnings, the two read as a
 * contradiction: "audio detection is not enabled" next to a switch that is on.
