   Reglas:
     · Fondo siempre blanco puro (#FFFFFF). Nunca crema.
     · Un solo acento cromático por bloque. El acento varía por sección.
     · Tipografías: Instrument Serif · Inter · IBM Plex Mono.
     · Sin gradientes coloreados, sin iconos decorativos, sin estética SaaS.
     · Bloques alineados a la izquierda. Líneas divisorias finas.
