Hard rule (applies to every VR ticket): the non-VR path must not lose quality or FPS. All VR work is optional and only affects the VR path: no new per-frame work, memory, pipelines or device extensions when VR is off; each milestone is gated by a fixed-camera GPU/CPU timer A/B of VR-off against main before it lands.

OpenXR loader (runtime-loaded, like the DLSS shim; new 3p package), XR_KHR_vulkan_enable2 hooks in instance/device creation, headset GPU selection, XR swapchain, xrWaitFrame/BeginFrame/EndFrame loop, startup-only VR toggle. Demo: headset shows a cleared/test image; desktop unchanged when VR is off.

Part of #1072.
