Stream the offers of one property as suppliers answer. Takes the body of POST /v1/stays/fares (searchSolutionId + propertyId, or a direct property block) with an optional currency, and accepts a bearer token or a guest session token. Each offer is one combination of room, board and cancellation terms with one price; no supplier is named. The route answers 404 while the feature is off. A malformed searchSolutionId, an unknown or malformed propertyId, or an expired search whose property is no longer known returns 410 OFFER_EXPIRED. A repeat request for the same property replays the newest snapshot without new supplier calls.

Frame vocabulary (event: names on this stream):

• offers — the whole offer set; revision rises by 1 per frame. An offer's id, total and freeCancellationUntil never change within a set; later frames add offers.
• done — terminal frame, data: {complete, reason} with reason one of all_suppliers, deadline, no_rates. An empty result is offers: [] followed by done with no_rates.
• error — terminal frame on failure; data: {"code": ..., "message": ...} with PROVIDER_ERROR or MAX_NIGHTS_EXCEEDED as on the fares stream, or INTERNAL_ERROR when an offer could not be stored.
