This doesn't work quite the way I had thought. This won't work but was a fun learning experience. |

This doesn't work with Suspense semantics, but it did lead to a potential new primitive (Shadow) where it's non-template children render in the order they land allowing OOO streaming semantics within a single view with ZERO JS. Deterministic UI order can be achieved with slot names even on function Wrapper({ children }: { children?: JSX.Children }) {
return (
<Shadow ext="section">
<Shadow.Template>
<p>before</p>
<slot>loading</slot>
<p>after</p>
</Shadow.Template>
{children}
</Shadow>
);
}
async function Component({
children,
delay,
}: {
children?: JSX.Children;
delay: number;
}) {
await new Promise((r) => setTimeout(r, delay * 500));
return <p>resolved {children}</p>;
