The first emotional decision happens at the door.

A guest scans the environment for signals about whether they belong before the program has begun. The faces at the registration desk, the imagery on the banners, the tone of the room itself, each one returns a verdict. If the signals come back negative, the guest withdraws into a defensive posture, hesitating to initiate conversations even when they arrived ready to network. The room shrinks for them, and no programming choice later in the day recovers what was lost in the first sixty seconds.

For organizers who treat the entry sequence as logistics rather than emotional architecture.
