# FUZZ_PARALLEL limits the number of fuzzing workers; each one keeps a
# 100 MB shared-memory file in the temporary directory.
# FUZZ_MINIMIZE is the time spent minimising each new input (default 0):
# minimisation stalls FuzzInspect for minutes, so short runs skip it; a
# failing input is still saved under testdata/fuzz as found.
