/**
 * Shared by the HQL chapter (15) and the Criteria API chapter (16) — both posts use the
 * same Employee/Department pair in their examples, so one real mapping backs both rather than
 * two near-duplicates.
 *
 * <p>Named {@code QueryDept} (entity name, via {@code @Entity(name = ...)}), not {@code
 * Department}, because chapter 06's {@code naturalid.Department} already claims that entity
 * name in this same persistence unit -- Hibernate requires distinct entity names project-wide,
 * not just distinct class names.
 *
 * <p>Docs: docs/15-hql-queries.md, docs/16-criteria-queries.md.
