asge::game::resources::UIHitList
Registry-wide UI hit-test list for the frame just drawn, back to front.
#include <HitEntry.hpp>Opt-in: only populated when this resource has been set (via Registry::SetResource<UIHitList>({})), and only then does RenderSystem rebuild it every frame from that frame's draw order. systems:: UIInteractionSystem walks it back-to-front (frontmost/topmost entity wins ties) to resolve which UIButton, if any, the pointer is over.
