/* Sentinel WELCOME splash - mail login edition (2-second cut).
   Treatment reused from the Sentinel Command login splash: Sentinel
   black + emerald (#00e676) + white ONLY. Animation timeline is the
   Command original compressed into ~1.3s so the whole splash,
   including the JS fade, is gone by 2s. The splashCssBackstop
   animation at the end of the .splash rule is the third, pure-CSS
   dismissal layer: even with all JavaScript dead, the overlay hides
   itself at 2.9s and the login form underneath is never blocked. */
