   Cada sección fluye de forma natural, con ritmo vertical ajustado.

   Paleta: un único matiz azul (217°) en intensidades distintas + neutros
   de matiz frío, con saturación contenida. Proporción 60-30-10:
   fondo azulado claro (60), superficies y secciones azul marino con
   texto (30), azul de acento (10). El azul marino se reserva para
   secciones de contenido; cabecera y pie permanecen en superficie clara.

   SISTEMA TIPOGRÁFICO
   Todo estilo de texto (familia, tamaño, peso, altura de línea, espaciado,
   mayúsculas) se define aquí con variables. Cada grupo tiene niveles con
   jerarquía fija; el orden se valida con `node check-tipografia.js`.

   Protocolo de cambios:
   - Un cambio pedido a un nivel se aplica a TODA la página.
   - Si el cambio es del grupo completo, se escala parejo conservando la
     jerarquía; si es de un solo nivel, se avisa si rompe el orden.

   GRUPOS Y NIVELES (de mayor a menor jerarquía)
   1. Títulos:             title-1 principal > title-2 subtítulo > title-3 tarjeta > title-4 ítem
   2. Cuerpo de texto:     body-lead introductorio > body párrafo > body-sm secundario > body-xs nota
   3. Etiquetas y datos:   label rótulo > meta dato > badge insignia
   4. Navegación y marca:  brand-name > nav / brand-sub
   5. Botones y enlaces:   btn botón > btn-sm filtro > link enlace
   6. Formularios:         form-label / form-input / form-note
