/* Muchas páginas (auditoría de diseño 2026-07-23) usan clases de color de Tailwind

   fueron pensadas para el tema oscuro por defecto y se vuelven ilegibles en Clásico
   (fondo claro). En vez de editar ~40 archivos, se remapean acá: como app.css carga
   después de tailwind.css con la misma especificidad de clase, esta declaración gana
