DESK — LAB

BTC price × stablecoin dry powder

One chart, two sources. BTC price as candles, and total stablecoin supply — the sidelined "dry powder" that can rotate into risk — as an overlay on its own scale. A proof that the desk can fuse our own series onto price with Lightweight Charts. Swap the overlay for whale net-flow or any on-chain series; the plumbing is identical.

How it works — the page loads /assets/vendor/lightweight-charts.js (self-hosted, Apache-2.0) and one same-origin JSON baked at build time by tools/lab_chart.py. Price is a CandlestickSeries; the overlay is a LineSeries pinned to a separate left price scale. To merge real whale data, point lab_chart.py's overlay at an on-chain net-flow series — same [{time,value}] shape. Advanced Charts (custom datafeed) is the upgrade path if the desk wants the full TradingView terminal UI.
