and ID numbers are found and replaced with realistic fakes — the same
fake value every time the same real one appears.

How it works
Structured PII (emails, phones, SSNs, credit cards, IP addresses, ID numbers)
is matched with patterns and, for credit cards, a checksum.
Names and company names use NLP plus rules tuned for common document patterns.
The same real value always becomes the same fake value everywhere it appears.
