/* ---- SIGNAL FLOAT ----
   The one 3D object on the page, pinned to a single fixed spot in the
   viewport — no card, no border, no background, and critically: no
   travel. It does not slide, drift, or chase anything as you scroll.
   All of the scroll-reactivity lives in the object itself instead — a
   loose scatter of points at the top of the page that steadily pulls
   together into a solid wireframe icosahedron by the time you reach
   the bottom (see run3D in JS), plus its own constant rotation. That's
   the whole animation. JS only ever touches `opacity` here, fading it
   in once you're past the hero and out again near the page's end — no
   CSS transition, since the JS-side easing already supplies that. Sits
   vertically centered in the viewport by design so it reads as a fixed
   anchor point rather than "attached to a section." Non-interactive —
   never intercepts a click or scroll. */
