Features: Root entry point with discovery links, User and Order resources with HAL _links and _embedded, conditional actions (pay, cancel, refund) based on order status, pagination with prev/next/first/last links, HATEOAS client that never constructs URLs manually, content negotiation for application/hal+json, and tests verifying link traversal.
