Your first message after signing up starts the build
When you sign up and send your first message, it now goes straight to the agent. Before, many new accounts saw the pricing screen first, even though their free credits had already arrived, and had to send the message again.
Playcode now checks your balance with the server before it shows pricing, so the pricing screen opens only when you are really out of credits. If the check cannot reach the server, you get a short message to try again, and your text stays in the box.
