Can static variables exist anywhere in C++ other than in a class? If so, what behaviour do they exhibit? I assume they’re not being shared between instances as there is no object.

Yes.
The lifetime of a static object is the life of the program and the linkage of the object is internal if the variable is declared at file scope (and no linkage if defined at block scope).
