/* Panel de TekyTap. Valores del kit de marca de Tekysoft
   (agency_tekysoft/docs/brand/tekysoft-brand-kit.md): Manrope, navy, azul como
   único acento en modo claro, verde solo para "correcto", escala Slate, radios
   8/12/16 y sin gradientes. Sin compilación: este fichero se sirve tal cual.

   Pensado primero para el teléfono, donde se usa como una app: barra de pestañas
   abajo, botones de 48 px y zonas seguras de la pantalla. Desde 840 px la misma
   barra sube a la cabecera. */
