The fixed-baud window counted down a uint32 where almost every window fits 24 bits; the countdown now takes avr::uint24_t when the poll budget allows (the autobaud budget's own choice), uint32 past 16.7M polls — four bytes off every fixed-baud image on every chip, the full suites green on the changed window. The README size table is refreshed — its autobaud column had also gone stale by the no-assembly pass's measurement-loop win, which nothing gated: sizes.py check-readme now runs as the gate's final stage, where every tree is freshly built and the table can actually be held.
