/* ==========================================================================
   SUN Liner Portal - sign-in screen.

   The legacy sign-in (sun_blazor_ref_files/loginscreen.png): a port photo
   behind a frosted card with an orange edge, the SUN Liner mark, two fields
   and one button. Plain HTML on purpose - the form posts to an endpoint that
   writes the cookie, so nothing here needs a circuit or DevExpress.

   The three port photographs cross-fade slowly behind the card.
