 IMPORTANT:
 - Only extract recipients explicitly mentioned in the document
-- Email is mandatory for every recipient (real, sample, or placeholder derived from the document text)
 - Default role is SIGNER if unclear (signature lines = SIGNER)
 - Signing order starts at 1 (first signer = 1, second = 2, etc.)
 - If no clear ordering, omit signingOrder
