An Operand represents one side (left or right) of a condition comparison. It can refer to a blackboard variable by name (Variable mode), hold a literal numeric constant (Const mode), or represent an external data input pin on the node (Pin mode).

C++14 compliant — uses std::variant via mpark::variant polyfill is NOT required here; the union is modelled with explicit tagged members to stay within C++14 without extra dependencies.
