   Lumen Hub — sistema visual
   ═══════════════════════════════════════════════════════════════════

   Rediseño con el lenguaje visual de Stripe: fondo claro, una sola
   familia tipográfica, tarjetas blancas con sombras muy suaves, un
   morado de marca reservado para la acción principal, y color usado
   solo donde significa algo (un estado, un riesgo) y nunca de adorno.

   Tres decisiones que explican casi todo lo demás:

   1. El fondo NO es blanco puro (#f6f9fc). Sobre blanco puro, una
      tarjeta blanca no tiene contorno y toda la pantalla se aplana.
   2. El morado es escaso a propósito. Si tres cosas en pantalla son
      moradas, ninguna es la importante.
   3. Los datos mandan sobre la decoración: tablas densas, números
      alineados a la derecha y cifras tabulares. Es un panel de
      trabajo, no una página de marketing.
