/* ===========================================================================
   Tessen — security page only
   ---------------------------------------------------------------------------
   This sheet loads after assets/css/tessen.css and every rule in it is scoped
   to .page-security. Nothing here redeclares a shared component class at the
   same specificity, so the responsive rules in the shared sheet keep winning
   on every other page. Colours come from the --sf-* surface set, so each block
   follows whichever tone its section declares.

   New stems on this page: crest (page header), ctl (control rows), cipher
   (encryption schematic), region (residency), attest (report slots). None of
   them collide with a stem already in use.
   =========================================================================== */

   is the one already established in the security section: a thumbnail pins in
