// GPU timing capability. The graphics module (LAYER 3) provides a live
// implementation; lower-layer consumers (e.g. the profiler module) query it via
// eve::cap::query<I>() and cope with nullptr (when graphics is absent / disabled).
// This keeps the interface in common/ so layering is not violated.
