 * Kalshi-style orderbook: left-aligned column spanning full chart height.
 * Labels decelerate as they rise — fast entry at bottom, slow drift at top.
 * Speed driven by two signals:
 *   1. swingMagnitude — price momentum (proxy for activity)
 *   2. orderbook churn — how much the bid/ask data itself is changing
 * Whichever signal is stronger wins. Works with both demo and production data.
