@@ -31,6 +31,11 @@ y el versionado sigue [Versionado Semántico](https://semver.org/lang/es/):
   - Detalle ampliado al pasar el ratón (o tocar en móvil) sobre el indicador
     de estructura: número exacto de entradas y salidas, valor en sat y BTC,
     bloque, comisión y tasa. Mantiene la vista limpia y el detalle a mano.
+- Contraste de texto mejorado en toda la aplicación. El texto secundario
+  (descripciones, datos de apoyo, el texto dentro de las casillas y el pie de
+  página) era demasiado tenue y costaba leerlo. Se ha subido su contraste en
+  los cuatro temas, manteniendo la jerarquía visual: el texto secundario se
+  sigue distinguiendo del principal, pero ahora se lee con comodidad.
