// `panNumber` all lowercase into these.
// * Native-script terms, per this module's multilingual mandate (the Aadhaar
// and My Number patterns already carry theirs). CJK terms match as
// substrings — CJK text does not put `[\W_]` between a word and the
// digits that follow it.
// substrings because CJK sentences provide no `[\W_]` boundaries around a
// word — the case this buys is a keyword embedded mid-sentence
// (`…信用卡账单 <PAN>`). It does not buy `卡号<PAN>` with the digits
// directly attached: there `CC_RE`'s own leading `\b` already fails
// (CJK is `\w`), so the run is never a candidate in the first place.
