The dependency sneaked in when type hints were added, and imported some parts of tiled.server into modules that did not used to depend on it. I think the best solution is to rework to remove the dependency.

[DiamondJoseph]

# All dependencies are optional; it depends on whether you are running
# a client or server (or both) and what data structures you care about.
# Use pip install tiled[all] to get everything.
dependencies = []

Is there reason to continue this? Minimal_client and minimal_server have overlapping requirements. I would add pydantic to these, and elevate them to core dependencies. Pydantic is our serialisation library for client/server communication.

# overlapping requirements of minimal_server, minimal_client
