   UniTradeX — "Modern Fintech Dark" skin
   Loaded LAST on every page so it refines the look without
   touching layout. Visual surfaces only (color, border, shadow,
   radius, gradients, spacing) — no display/position/grid changes
   that could break existing layouts. Token-driven so light mode
   still works.
