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.

Per-eye RenderView refactor completed, VK_KHR_multiview for raster passes, fused stereo cull, fixed/eye-tracked foveation via the VRS path, visibility mask, depth layer, async compute re-enabled, GI re-evaluated for VR.

Part of #1072.

Folded into #1075 (2026-10-26): the plan now goes straight to layered stereo (multiview raster + compute over view layers + shared once-per-frame work) instead of a serial render-twice M2 followed by this M4. Foveation / VRS and async re-tuning remain follow-ups under #1075.
