- IVROverlayView reads system overlays (systemui, HeadsetView) but not Steam's dmabuf-backed panels - SteamVR systemui scene graph accepts injected nodes (DOM elements with buildNode; submit via module 5723's scheduler): reparent-to-panel + panel-anchor + transform + panel shows live crops of Steam's window at any 3D offset, and our own dmabuf overlays (needs SetOverlayMouseScale) - hvgrab: headset-view capture for verification
