/* ── CON TU IA (ES /es/agentes-ia) ──────────────────────────────────────────
   La página que explica que Publicit se lleva hablando con tu asistente de IA.
   Sistema de la home (home.css) en su versión de noche: el fondo del globo,
   titulares a dos tonos con la Forma DJR Banner, medios redondeados, nada de
   iconos. El mini tutorial para conectarlo va en blanco, tras «Pídelo».

   1 · La historia (agents-story.js): a la izquierda se lee (el chat, que es
       Claude) y a la derecha se ve: cada punto del lienzo es una pantalla.
       El scroll es libre. Sin JS todo se lee en orden.
   2 · Pídelo · 3 · Cómo conectarlo (en blanco) · 4 · La última palabra
   5 · Sesión real · 6 · FAQ
