/*
  Silvana Book — Markets (Terminal layout)
  Built on design tokens from ../styles-lib/tokens/*.

  Layout concept is deliberately NOT a repeating grid of price cards
  (that's the competitor's — Temple — pattern, see README). Instead this
  page is a single asymmetric "terminal" workspace: a scrolling ticker
  tape, a compact watchlist, and one large detail panel with a real
  order-book depth chart for the selected pair — closer to how a trading
  terminal is actually organized than to a marketing grid.
