* Render a GLTF/GLB model and signal when its primary scene becomes visible.
*
* Resolves a provided model URL to an absolute URL when running in a browser, loads the GLTF, and renders its scene as a primitive. After the scene is available, schedules a single animation frame that records the visibility timestamp on `window.__lod0VisibleAt` and dispatches a `CustomEvent` named `"lod0:visible"` with `{ ts }` in `event.detail`.
