/* =========================================================================
   NiftyOptionTrader — dark trading-terminal design system (Phase 0)
   Layered on top of Bootstrap 5.3's built-in dark mode (data-bs-theme="dark"
   set in App.razor). We deepen the palette and add brand/status tokens here
   rather than fighting Bootstrap — every existing page already uses plain
   Bootstrap classes (card/table/badge/btn/alert/form-control), so retuning
   the underlying CSS variables reskins the whole app without rewriting
   every .razor file. Later phases restyle individual pages on top of this.

   with an equal negative margin so this reaches the sidebar's edge and the window's right/bottom
