        '401':
          description: Unauthorized. May indicate (a) bad/expired token — re-auth and retry once, OR (b) missing required params (validation errors are returned with status 401 today, not 422). Inspect the `message` field. Token errors may also break the standard envelope (e.g. `{message, status_code}` with no `status` key).
        '429':
          description: Rate limit exceeded. Back off 250 → 500 → 1000 ms.
        '500':
          description: Server-side error. On `/deeplink/generate`, a 500 is also returned for invalid `offer_id` or non-whitelisted destination URLs — these are PERMANENT client errors despite the 5xx code. Inspect `message`; retry only if you have reason to believe the request was previously valid.
