Key elements of the project:

1. Dual Web Servers: Two independent web servers running on the same ESP32, on ports 80 and 81.

2. Password Protection: Users must log in with a predefined password.

3. Shared Chat History: Both servers read from and write to the same chat history string.

4. Web Interface: A modern, responsive web interface for sending and receiving messages.

5. Memory Management: The chat history is limited to prevent memory overflow.
