/*
 * Trading desk shell — the outer chrome only. The tab content is each service's own front end,
 * embedded through the gateway with its topbar/statusbar hidden (?embed=1). Terminal-style dark
 * UI, shared with orderbook / risk-engine / trading-system — see the palette in
 * workspace-config/CLAUDE.md -> "Live demo look and feel". The tokens below are copied from
 * orderbook's app.css so the whole family reads as one product.
