Historical liquidity heatmap

Scrub backward through HL's L2 order book. Walls show up as continuous horizontal bands; the mid-line trail tracks how price interacted with them. Backed by the Phase 15.1 collector + Phase 15.2 query endpoint — see-through to where bid/ask depth actually sat at any moment in the last 7 days, not just whatever filled in while you were watching the page.
