/* =============================================================
   PANTALLAS DE ACCESO (login, recuperar clave, restablecer clave)

   Antes cada una de las tres vistas repetia su propio bloque <style>
   inline -- 276 lineas en total, con los mismos tokens copiados y con
   los @media / @keyframes escapados como @@ por estar dentro de Razor.
   Aca viven una sola vez.

   Los colores salen de las variables de site.css para que el acceso y
   la aplicacion sean el mismo sistema. Antes el login usaba #1e3a5f y
   la app #1e2a3b: al entrar, el header cambiaba de tono.
