/* ============================================================
   BRUNINDIA LLC — sitio institucional
   Concepto: "manifiesto de embarque" — tinta, papel kraft, sello óxido.

   Tipografia: DOS familias, a proposito.
     · Figtree — titulos y texto. Geometrica y redondeada, en el mismo
       idioma que el wordmark del logo (antes habia una condensada
       industrial que peleaba con la marca).
     · IBM Plex Mono — solo datos: referencias, pasos, labels del
       formulario. Es lo que le da el aire de documento de carga.

   Tema: CLARO FIJO, decision deliberada. Es un sitio corporativo que se
   muestra a clientes; conviene que se vea igual en todos los dispositivos.
   Por eso no hay bloques de modo oscuro ni selector de tema.
