/* ==========================================================================
   Sabah Diabolo — Back-Office Shell (AdminShell.cs)
   --------------------------------------------------------------------------
   ONLY the chrome that is unique to the office workspace lives here.
   The sidebar, drawer, nav, layout wrapper and all components now come from
   theme.css + app.css — the same ones the public/contingent/judge pages use —
   so the two shells cannot silently drift apart again.

   Unique to admin = the Tier-2 tournament workspace bar (Rule R1), the master
   results switch, the tournament menu dropdown, and the sidebar user footer.
