oa::EngineRequirements

Optional services that the selected device must provide. Compute is always required. These predicates constrain physical-device admission before the logical device is created; they do not expose kernel selection or vendor policy. Presentation readiness proves a graphics queue and swapchain support for an instance created with surface extensions. The eventual Presenter still verifies the concrete window surface.
