/*
  REDISEÑO COMPLETO -- direccion formal / "mental": negro, blanco y cian-
  menta desaturado como unica familia de color, sin acentos vivos
  (nada de naranja/rosa/violeta). Los 3 productos se diferencian por
  TONALIDAD dentro de esa misma familia cian (mas profundo, medio, mas
  claro), no por colores distintos -- mantiene todo dentro de una sola
  identidad seria en vez de sentirse como 3 marcas separadas.
  Tipografia: Fraunces en tamaños grandes para frases-gancho con mucho
  peso visual (nada de parrafos largos en el hero), Inter para texto de
  apoyo, JetBrains Mono para precios/caracteristicas tecnicas.
  Layout: home de una sola pantalla de impacto + 3 tarjetas de producto
  grandes (clicables, cada una a su propia pagina), paginas de producto
  independientes con su propio hero tonal.
