/* PhantomShield dashboard.
   The look borrows from airmail stationery: pale blue paper, navy ink, the
   red-and-blue striped edge, typewritten addresses, and a rubber stamp for
   the one thing that needs attention (a possible leak). No web fonts and no
   third-party requests: everything here is served from this site. */
