/**
 * Config validation: the raw object a project's config file exported, held to
 * the LookoutConfig shape with precise messages.
 *
 * Hand-rolled rather than a schema library: the config is small enough that a
 * library would cost more than it saves. Split from config.ts because loading
 * (finding the file, importing it, zero-config synthesis) and validating are
 * edited for different reasons, and the file had hit the line ceiling. Split
 * again into config-validate-parts.ts for the same reason: this file is the
 * composition, one field after another, and the pieces live next door.
