    Class MeshPicker

    Asynchronous backend-neutral GPU object picker.

    Selection coordinates are CSS pixels relative to the Stage canvas. Each request renders a dedicated object-ID pass through the active backend and asynchronously reads the requested rgba8unorm texels. No CPU ray-casting fallback is used.
