/* ── Spline Integration ────────────────────────────────────────────────
|
||||
*
|
||||
* WHEN YOUR SPLINE SCENE IS READY:
|
||||
*
|
||||
* Option A — HTML (simplest):
|
||||
* Open index.html, find #spline-layer, delete .spline-placeholder,
|
||||
* and paste in:
|
||||
*
|
||||
* <spline-viewer
|
||||
* url="https://prod.spline.design/YOUR_SCENE_ID/scene.splinecode"
|
||||
* events-target="global"
|
||||
* ></spline-viewer>
|
||||
*
|
||||
* Option B — JavaScript:
|
||||
* Call window.Lumerel.loadSplineScene('https://prod.spline.design/…');
|
||||
* This removes the placeholder and injects <spline-viewer> for you.
|
||||
*
|
||||
* Option C — @splinetool/runtime (advanced):
|
||||
* import { Application } from '@splinetool/runtime';
|
||||
* const app = new Application(canvas);
|
||||
* app.load('https://prod.spline.design/YOUR_SCENE_ID/scene.splinecode');
|
||||
*
|
||||
* For interactive scenes (mouse/touch on the 3D layer), call:
|
||||
* window.Lumerel.enableSpline()
|
||||
*
|
||||
* ─────────────────────────────────────────────────────────────────────── */
