/* =====================================================================
   Exploremos: página de presentación pública ("/" sin sesión)
   Independiente de app.css (sin Bootstrap), con los tokens oscuros de "Noche clara"
   (docs/DISENO.md, app.css § 1). La protagonista es la propia interfaz de la app.
   Movimiento: un solo sistema (tokens --dur/--ease de la app), solo transform y opacity.
     · Hero: la pantalla de Inicio se arma (landing.js) y la luz sigue al puntero.
     · Recorrido: teléfono fijo cuyo contenido cambia por paso (landing.js, IntersectionObserver).
     · Entradas y riel de progreso: animation-timeline: view() con respaldo por IO.
   Sin JS o con movimiento reducido: estado final.
