   MoraBanc — Asesor Financiero IA
   Sistema visual corporativo alineado con morabanc.ad.

   La paleta NO es inventada: sale de las variables CSS reales del
   sitio de MoraBanc (clientlib-base.css / clientlib-site.css):
     --darkblue    #0a3550   color dominante del sitio (117 usos)
     --banner      #114274   navy de banners
     --accent      #f1c657   gold de marca (CTA, breadcrumbs)
     --accent-soft #f7dd9a   hover del gold
     --lightblue   #e8f1f8   superficie suave (cards, mosaicos)
     --brand-light #82add8   azul de marca
     --text-link   #64a0d0   link
     --gray-100    #f8f8f8   superficie
     --gray-240    #e7e7e7   borde de card
     --gray-300    #d9d9d9   borde
     --gray-500    #898989   texto secundario
     --positive    #04aa6d   ok
     --negative    #f0421c   error
     --alert       #e7891c   warning

   Tipografia: MoraBanc usa Oblik (titulares) + Source Sans Pro (texto).
   Aqui NO hay build step ni fuentes externas (el front pesa 232 KB y no
   descarga webfonts), asi que se declara la pila de sistema equivalente:
   se mantiene la jerarquia y el ritmo tipografico sin 300 KB de fuentes.
