/**
 * Annotation config types — the named-score-type contract for AnnotationInput
 * (M12). Follows Phoenix's three-type model (categorical / continuous /
 * freeform); Langfuse's BOOLEAN is categorical-of-two and CORRECTION is
 * system-only, so neither adds to a controlled human input. The config is a
 * plain descriptor the consumer owns (fixture or backend store) — the DS
 * component is config-driven and stateless.
