/* ========================================
   INDEPAR - Chrome del sitio (nav + footer) para páginas de molde standalone
   Extraído de styles.v2.css (secciones NAVIGATION, FOOTER, body offset y
   sus reglas responsive) para las calculadoras: solo selectores de clase
   más el offset del body — cero colisión con los estilos propios del molde.
   Única adaptación: los font-stacks usan los fallbacks del molde
   (Merriweather,Georgia,serif · Inter,-apple-system,...) porque estas
   páginas no cargan webfonts.
   Si el nav o el footer cambian en styles.v2.css, regenera este archivo.
