Core intent: - Support multiple terms/eligibility/constraints/price points for the same Resource(s) - Support dynamic / on-the-fly offers (e.g., bundling, combinational discounts,  eligibility changes, capacity-aware pricing)  This mirrors the role of Offer in current Beckn (and schema.org patterns), but keeps the shape minimal and composable via `beckn:offerAttributes`.",
