Layout regrouped by relationship, not size: the setup-in-focus card and the radar sit side by side (they are one decision surface), the four account ribbons move directly above the open positions they describe, and a new performance chart closes the page. - Radar rows are selectable: clicking one swaps the focus card to that setup - including below-gate rows, whose card shows a muted "rank N / below gate" badge and the disqualify reason in the footer, with a "back to top pick" reset. The row currently in focus is highlighted; ticker links still deep-link without selecting. - Performance chart (the mockup's missing piece): new GET /paper-trades/equity-curve computes, per benchmark trading day since the first paper trade, the book's cumulative P&L (realized + mark-to-market from stored OHLCV) vs the same cost basis riding SPY over each trade's window (benchmark_prices). Pure curve math in paper_trade_service with unit tests; hidden until there are 2+ points of data. Frontend renders both lines with crosshair readout, zero baseline, and direct end labels. Backend unit suite: 501 passed. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>
