One five-letter word a day, same word for everybody

Six guesses, one hidden five-letter word, and green or yellow tiles telling you which letters are correctly placed or merely present. Everyone in the world gets the same puzzle each day, which is why a small grid of coloured squares became a shareable result rather than a score.
The daily limit is the whole design: one puzzle, no rematch, and a shared answer that turns a private guess into a conversation with everyone you know.
