/* ihasvpn.org
   Its own palette and its own navigation, on purpose: the sibling sites
   (ihasmail.org, inbuxa.org) share a teal-navy sidebar shell, and a VPN
   should not look like a mail server's brochure.

   The palette is night traffic. The ground is a deep indigo, the colour of
   a network diagram after dark. The accent is signal mint -- the green a
   VPN client lights when the handshake lands -- and it is a cousin of the
   shield's teal in the mark, so the logo sits in it naturally. Violet is
   the tunnel: the route line, gradients, the second voice. The cat's
   orange (#F9A34B) stays as the warm highlight, the same as everywhere.

   Dark is the base definition on :root, and it is what everybody gets
   until they say otherwise -- the system preference is deliberately not
   consulted. Light exists only under [data-theme="light"], which the
   toggle sets and localStorage remembers. No colour is defined *only*
   inside that block, so a token can never go missing in the dark. */
