/*
 * Ecranul de autentificare IT4All.
 *
 * Fundalul: campul de particule preluat din pagina animata a it4all.ro. Canvas-ul
 * deseneaza reteaua, ".it4all-veil" adauga vignetarea care da adancime, iar
 * ".it4all-grain" o granulatie fina care rupe benzile din gradiente.
 *
 * Formularul: panou de sticla deasupra campului. Selectorii sunt cei reali generati
 * de roundcube - butonul este "button.mainaction.submit", NU ".btn-primary"; cine
 * stilizeaza .btn-primary nu vede nicio schimbare pe ecranul de login.
 *
 * Accesibilitate: la "prefers-reduced-motion" campul si animatiile dispar, iar
 * formularul ramane complet utilizabil - de-aia contrastul lui nu depinde de canvas.
