The 2023 column omitted the $89,901-$90,000 -> $553.70 row (shifting every later amount by $10 through $94,200), did not encode the card's three intentionally $200-wide asterisked ranges, and duplicated the 91,701/91,801 thresholds (SingleAmountTaxScale sums duplicates -> 787.40/767.40 reductions, ~$390 tax understatement). Re-keyed all 45 2023 entries; 44/44 card rows now match by midpoint probe, and the 2021/2022/2024/2025/2026 columns are verified bit-identical to main.

Fixes #9026. Not a backward-leak — a transcription defect found while auditing the leak candidates (#9024).
Card (TaxBrackets_2023.pdf, verbatim): rows step the reduction down $10 per $100 from "$89,601 $89,700 4.70% $583.70" to "$94,101 $94,200 4.70% $163.70", then "$94,201 $100,000 4.70% $153.70"; note: "The income ranges indicated with an asterisk (*) extend an extra $100 intentionally" (*$90,001–$90,200, *$90,901–$91,100, *$93,601–$93,800); PE omitted "$89,901 $90,000 4.70% $553.70" and duplicated thresholds 91,701/91,801, which SingleAmountTaxScale sums (787.40/767.40 → ~$390 understatement).
Verification:
Tests: three card-anchored cases — the formerly missing row (89,950 → 3,673.95), an asterisked range (90,100 → 3,691.00), and the formerly duplicated zone (91,750 → 3,918.55). 40/40 AR income tests pass.
