# --no-fuzzy-matching: when a *new* source string is added, Babel's fuzzy
# matcher otherwise guesses a "close" existing translation and marks it
# `#, fuzzy` in every language catalog. Those guesses are (a) usually wrong
# (e.g. a new "valuename" string mapped onto an unrelated "table name"
# translation) and (b) counted by check_translation_regression.py as a
# regression, so every PR that merely adds a translatable string failed the
# babel-extract check. Disabling fuzzy matching means new strings land as
# cleanly untranslated (empty msgstr) instead — accurate, and no spurious
# regression. Renames likewise drop the stale translation rather than
# stranding a wrong guess; the string is re-translated by the community.
