Same resource, other clients

Read from the server itself, by connecting to it and calling resources/list on 19 October 2026. A listing does not declare its resources, so asking is the only way to know them, and this is what the server actually offers rather than what its listing claims. Names only are stored; connect the server for each resource's type and contents.
