/* Proyecto Gen AI v4 "Noir" — Design system (docs/proyecto-genai-noir-especificacion.md)
   Cine noir + diario/revista de los 60 + papel y tinta + foto B/N alto contraste.
   Negro dominante, blancos duros, sin bordes redondeados, sin glows de producto SaaS.
   Un único color saturado por historia — se define inline vía --accent, nunca acá.
   Tipos: Libre Caslon Display (editorial/titulares), Archivo Narrow (condensada:
   nav/kicker/meta), Inter (cuerpo/UI), DM Mono (datos auxiliares/timestamps). */
