/**
 * In Domain Driven Design, a Reference is a special type of Domain Literal that represents a reference to another Domain Object.
 *
 * A Domain Reference:
 * - contains only the identifying properties of the referenced object
 * - is immutable (like all Domain Literals)
 * - is used to refer to Domain Entities or Domain Events without including their full data
 *
 * The purpose of a Domain Reference is to enable lightweight references between domain objects without circular dependencies or data duplication.
 *
 * For example:
 * - A `SeaTurtleRefByUnique { seawaterSecurityNumber: string }` is a reference to a SeaTurtle by its unique key
 *
 * Note:
 * - Domain References are typically created automatically via `DomainEntity.RefByUnique` or `DomainEntity.RefByPrimary`
 * - You rarely need to extend a DomainRef directly
