Unknown preset '{}'. Available presets: calm

Error message

Unknown preset '{}'. Available presets: calm

What it means

Named settings preset application (bundled-settings mechanism): the requested preset name is not one of the shipped presets — currently only `calm` exists. The message lists the valid names so the caller can correct the request.
