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.

Curved UI wall (cylinder layer, quad fallback) with the full screen UI incl. HUDs, menu-button toggle, world-locked on summon, laser pointer (trigger/right click/scroll/drag), locomotion frozen while shown; wrist panel for IMs/notifications/dialogs; OpenXR actions + bindings; locomotion/turn; controller-ray world pick; fly cam with blink return; frame-rate safety governor; Preferences > Safety tab. Demo: log in, walk, click, chat, inventory, fly-cam, all in the headset.

Part of #1072.
