/* trade_timeline.css — "how each trade aged" feed.

 * Composes two patterns that already live in the engine:
 *   - the side-by-side teams layout from league_view.css (.lv-trade*)
 *   - the SVG trajectory chart from suite.css (.bb-traj*)
 * extended to two series. Shared chrome lives in base.css; only
 * trade-timeline-specific bits are here.
