Every Upstash command and Neon query now has a deadline (5 s and 8 s): the Redis client retried a hung connection past the browser's fifteen-second wait, and the Neon client had no limit. Usernames are NFC-normalised so a tone mark typed as a combining character is accepted and does not make two board members of one name. The debug key is compared in constant time. A panorama whose district the tree does not know fails the draw before a session is written, not /api/guess after it is consumed. The country branch of countPanos and the never-triggered per-city cap are gone.
