/* ============================================================
   3D SCROLL HERO  — fullscreen Three.js canvas, pinned on scroll
   ------------------------------------------------------------
   Markup contract (see index.html):

     <section.hero3d>              ← ~350vh tall, supplies scroll distance
        <div.hero3d__stage>        ← position:sticky, 100vh, the "pinned" frame
           <canvas.hero3d__canvas> ← WebGL surface, fills the stage
           <div.hero3d__overlay>   ← headline / CTA copy over the 3D scene
        </div>
     </section>

   Why sticky (not position:fixed) for the pin:
   the stage sticks to the top of the viewport for the entire scroll of
   the 350vh section, then releases on its own when the next section
   arrives — no manual show/hide bookkeeping, and it cooperates with the
   Lenis smooth-scroll (which drives real scrollTop) far better than a
   fixed element. It is also RTL-safe: only top/inset are used, never
   left/right.
