   CTA — PUERTA A LA BASE DE CONOCIMIENTO
   Bloque final reutilizable (portada y nota). Mismo idioma V2: mono, corchete
   en las esquinas, acento, glow LEVE. Sin scanlines, sin neón.
   🔴 Anima SÓLO transform/opacity y respeta prefers-reduced-motion.
   🔴 Sólo tokens de ROL: funciona en tema claro y oscuro sin tocar nada.
