The board, the home screen and the game-over panel, in Vietnamese, served by the Go binary as a static single-page app. The store is a reducer over ServerMessage and computes nothing. Validity, turn order, scores and the result are read from the wire, which is what lets one screen serve the bot now and online play later. Every Vietnamese string lives in one module, including the map from RejectReason to a message, so the server can send UI keys instead of prose. The word field is uncontrolled. A Telex or VNI input method composes a diacritic across several keystrokes, and writing the value back on each one cancels the composition. It is read on submit and cleared only there. The countdown is drawn against the server's clock, estimated from the ping round trip, and settles 300ms early so the ring never claims more time than the server allows. The screen owns the socket and the game while it is mounted, and gives the current game up on the way out. Asking for a game is stored intent rather than a condition inferred from the board being empty: clearing the board for a rematch is that same condition, so the inference sent a second StartBotGame and the server built two rooms that then destroyed each other. A test greps the built bundle for dictionary words and holds a size budget, so the wordlist cannot reach the browser unnoticed. Another reads the error codes out of the Go transport and fails when one has no Vietnamese message.
