A generalized, cross-domain Offer that captures the terms under which one or more Resources may be committed. 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.
