Concept definition

template<typename T>
concept comms::Displayable =  requires {
    { HasDisplayInfo<T>::display_info() } -> std::same_as<const DisplayInfo&>;
}

Detailed Description

True when T has display metadata — via a member display_info() or a HasDisplayInfo<T> specialization.

std::same_as<const DisplayInfo&> forces a reference return, ruling out a dangling reference to a by-value result.
