# vs 2025 ($1,975), out of step with the ~2.85% COLA applied to every other
# DP configuration and in conflict with the "-$22 when only one spouse is blind"
# footnote rule that holds for 2011/2017/2018/2025. The $3,031 value appears
# to be an Iowa HHS publication error (likely a transposed digit from an
# intended $2,031). Encoded as the COLA-consistent total $2,031, which
# preserves the 14-year footnote pattern; revisit if Iowa HHS corrects the
# page or issues a General Letter confirming the higher figure.
