* Open index.html → find #spline-layer → delete .spline-placeholder
* → paste in:

*
* ── Method B (JavaScript runtime) ─────────────────────────────────
* Call from console or your code:
* window.Lumerel.loadSplineScene('https://prod.spline.design/…')

* ── Method C (Interactive scenes) ─────────────────────────────────
* After scene loads, enable pointer events:
* window.Lumerel.enableSpline()
*
* The web component is already loaded via CDN
* in the of index.html — no extra imports needed.
