   Identidad visual propia — "Tinta de ciruela y papel"
   --------------------------------------------------------------------------
   Paleta:  ciruela profundo (tinta), papel crema, ocre quemado, verde musgo.
            Ninguna coincide con la paleta de una marca, banco o entidad
            tratada en los contenidos.
   Tipografía: serif editorial del sistema (Iowan Old Style / Palatino / Georgia)
            para títulos y lectura larga; sans del sistema para interfaz.
            Sin fuentes externas: no se envían datos a terceros al cargar.
   Iconografía: "sellos" propios — glifos de trazo de 1,75 px dentro de un
            círculo con anillo punteado ocre.
