/* Rediseño claro (v4), inspirado en el estilo editorial de las webs de pagos pero con identidad propia: fondo blanco, banda de degradado inclinada,
   titulares sobrios (600), mucho aire, tarjetas con sombras suaves en capas y demo de módulos con pestañas.
   Se carga después de style.css, v3.css y bloques.css, y antes de /brand.css (que puede redefinir los colores de marca).
   TODO color de identidad vive en variables: --g1…--g5 (degradado), --accent/--btn (marca), --navy; cambiar la marca = cambiar estas variables. */
