Searches ANSI-stripped output for LANG / LC_ALL / LC_CTYPE envvar substrings emitted by env / locale / printenv. Highest-priority key wins (LC_ALL > LANG > LC_CTYPE); POSIX value normalised to BCP-47: en_US.UTF-8 → en-US, pt_BR.UTF-8 → pt-BR, C/POSIX → und. Free-string registry value emitted directly. PII discipline: only the parsed locale value enters observations; surrounding output is read once for matching and dropped.
