/wordledaily sends a BotFather game card whose page plays one shared word per day, changing at 07:00 ICT. The server checks guesses, saves each player's board after every guess and keeps NYT-style stats. A win is reported with setGameScore, and in a group one live results message shows everyone's colour grids. /wordledaily_subscribe and /wordledaily_unsubscribe opt a chat or topic in to the 07:00 push: yesterday's recap, opening with the answer and the group's win streak, then today's card. The HTML5 game plumbing that noitu used is now shared in util/htmlgame, and the wordle word list and scoring live in wordle/wordlist.
