/**
 * Workflow states for EDM entities.
 *
 * The workflow system is shared with MEMBER_OFFER and RESORT, whose states
 * ("READY_FOR_CONTENT", "CONTENT_IN_PROGRESS") describe building an offer, not
 * getting an email built, tested and signed off. `workflow_tasks.status` is a
 * free-text column, so each entity type can carry its own vocabulary without a
 * schema change — this is the EDM one.
 *
 * Order is the intended progression: build it, hand it over, test it, review the
 * tested result, publish. It is NOT enforced: a reviewer sending something back
 * from IN_REVIEW is a normal day, and a state machine that forbids it just
 * teaches people to work around the tool.
