   MentorWallet — site.css
   Estilos propios de la landing, construidos sobre los tokens del design
   system (_ds/.../tokens/*.css, cargados vía styles.css).

   Incluye además los estilos de los componentes del DS que la página usa
   (Button, Badge, Card, StatCard). Antes los inyectaba en runtime el
   _ds_bundle.js; al aplanar el sitio a HTML estático se sirven aquí,
   verbatim desde la fuente del design system, para no depender del runtime.
