   LOGIN - Diseno compacto y responsivo del formulario.
   El video de fondo (definido en _LayoutLogin.cshtml) no se toca.

   NOTA: Este archivo vive FUERA de las vistas .cshtml a proposito.
   Razor interpreta cualquier arroba "@" dentro de una vista como inicio
   de expresion, por lo que las reglas at-rule CSS (keyframes, media,
   font-face) escritas dentro de un bloque style en la vista fallan con
   CS0103. Al estar en un .css estatico no hay conflicto alguno.
