- `MASSIVE_API_KEY` - Optional. If set, use real market data from Massive API. If not set, use the built-in simulator.

## Market Data Demo

A Rich terminal dashboard for eyeballing the live simulator — all 10 default tickers with
color-coded price/change, sparklines, an event log for notable moves (>1%), and a session
summary on exit. Runs for 60 seconds or until Ctrl+C.

```bash
uv run market_data_demo.py
