/* =====================================================================
   TRADEX — UI system v2  (dense, flat, app-like)
   ---------------------------------------------------------------------
   Design intent, in one line: a trading terminal, not a landing page.
   · tight vertical rhythm (10px gutters, 12px card padding)
   · tabular numerals so prices/tables never jitter
   · flat surfaces + hairline borders instead of glows and gradients
   · content uses the full width of a laptop screen
   · phones first: nothing scrolls sideways, tables become cards
   Zero dependencies. One file. Every class the views use is defined here.
