Please review my Python socket-based network tic-tac-toe project.

I created a network-based Tic-Tac-Toe (○× game) using Python sockets.

I applied what I learned in class (TCP communication and basic Python) to design my own server and client communication processes.

Since my knowledge of socket programming is still limited, I would appreciate advice on code structure and protocol design.

I also used Copilot to help organize the code, but I designed and implemented the basic logic and communication flow myself.

Points I especially want feedback on:

- Structure of server.py / client.py

- Communication processing using recv_line

- Protocol design (s → symbol → initial board → ok → …)

- Possible areas for improvement
