/* One stylesheet for the whole portal.
   KZN Business Training Centre, as on kznbusinesstraining.co.za: navy, green
   and cream. The green used for button fills is a shade darker than the
   website's, so white lettering on it stays readable. The fonts are the
   system's own — nothing is loaded from anywhere but this server, which is
   also what the Content-Security-Policy allows. */
