+ * Lumerel — 3D Homepage · main.js
+ *
+ * Responsibilities:
+ *   1. Spline 3D scene pointer-events toggle + runtime loader
+ *   2. Navbar scroll backdrop blur
+ *   3. Background video autoplay fallback (iOS Safari)
+ *   4. Waitlist button click hooks

+ *
+ *  When your Spline scene is ready, choose one of three methods:
+ *
+ *  ── Method A (HTML — recommended) ────────────────────────────────────
+ *  Open index.html → find #spline-layer → delete .spline-placeholder
+ *  → paste in:
+ *
+ *    <spline-viewer
+ *      url="https://prod.spline.design/YOUR_SCENE_ID/scene.splinecode"
+ *      events-target="global"
+ *    ></spline-viewer>
+ *
+ *  ── 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 <spline-viewer> web component is already loaded via CDN
+ *  in the <head> of index.html — no extra imports needed.
+ *
