# The published constraint is asymmetric, H0 = 71.6 (+3.9, -3.3).
# A Gaussian likelihood cannot represent that, so this file carries
# the mean of the two sides (3.6) -- deliberately not the tighter
# one. The asymmetry is small next to the ~5% total error, but the
# approximation is real: treat this as a broad, independent H0
# anchor rather than a precision measurement.
