Three words from 32 was ~15 bits — enumerable within a code's
lifetime against an unthrottled endpoint. Now: 64-word list, 4-word
phrases (~24 bits / 16.7M combinations), a per-connection cap of 5
failed claims, and a global backstop that voids all pending codes and
cools the endpoint after 30 failures in 10 minutes. Codes stay
speakable; a brute force now gets ~35 guesses against 16.7M before
the door closes.
