/*
 * Landing vibliv.com — sistema de diseño del bloque (v10, 2026-10-14: «la idea», cinco páginas).
 * Un solo lenguaje visual para la web y los vídeos («Unir las mentes»): casi negro con grano,
 * puntos de luz, hilos cian; verde para lo que existe, ámbar para las ideas y su procedencia.
 * CSP `style-src 'self'`: todo el estilo vive aquí, nada en línea. Tipografías autoalojadas en
 * /assets/fonts (Sora para titulares, Atkinson Hyperlegible para texto, IBM Plex Mono para datos;
 * licencia OFL). Oscuro por defecto; claro (tinta sobre papel) si el sistema lo prefiere.
