# Pin the BLAS / OpenMP backend behind numpy to a single thread. The daily
# routine's only BLAS call is np.corrcoef() on two 24-element vectors
# (decision_maker.py get_correlation, autotracer.py pass_by_density), so
# threading buys nothing — but an unpinned OpenBLAS spawns one worker per
# CPU on first use (dozens on shared-hosting boxes), which inflated the
# cgroup task count toward the old TasksMax=100 ceiling and added per-thread
# stack + glibc-arena memory against MemoryMax=1G. One thread is both
# correct and faster here (CLPRO-3118).
