/* ---------- 2 · qué hacemos (v15): «el sistema nervioso de la casa» ----------
   Gabriel 01/10/2026: "integramos cada sistema en un mismo control... mejorarlo muchísimo, más lujoso... muy tecnológico,
   que funcione con la ruedita, con el mouse, con el dedo, en todos los tamaños". A scene that stays while the page goes
   down (one gesture = one system, site.js): the house in section, drawn in light, fills the screen; its control centre is
   its heart. The panel says what each system is; the rail, like a dimmer, says where you are and takes you anywhere.
   Without the scroll effects (reduced motion, the 3.5 s fallback, previews that grow to the page) it is a still page:
   the whole house with every system on and the eight systems one after the other. */
