   FYF FACTORY — PLANO MAESTRO (F&F FACTORY S.A.C.)
   Dossier técnico sobre negro, iluminado con luz de arco.
   Negro #0C0C0D · Oro #F0A500 · Plata #9AA0A6
   Montserrat (titulares) · Inter (texto y anotación técnica)

   Reglas duras respetadas en toda la hoja:
   · Cero fotografías y cero background-image con fotos.
   · Cero bordes punteados o discontinuos (solo trazos sólidos).
   · Animación continua solo con transform / opacity / clip-path /
     stroke-dashoffset. Nunca filter, width, top ni background-position
     en bucle.
   · prefers-reduced-motion apaga todo y deja el estado final.
