   BUILGENT HOME — Ink & Paper editorial (2026-07-05)
   Tema claro para la HOME. Sustituye a styles.css SOLO en index.html;
   las subpáginas (sectores/, waitlist/) siguen usando styles.css.
   Contrato: mismas clases/IDs que consumen script.js, premium-fx.js,
   hero-story.js y los estilos inline de los mocks (var(--steel-*), etc.).
   Capítulos OSCUROS intencionales: hero (frames de vídeo), scrollstory
   (fotos), orbital (frames con fondo negro horneado), banner BF y footer.
