  Top-level namespace for the Risk Engine application.

  `RiskEngine` is a real-time portfolio risk monitoring system. Trades are
  ingested through `RiskEngine.TradeIngestion`, applied to per-portfolio
  `RiskEngine.Portfolio` processes, and the resulting exposure, volatility,
  and drawdown metrics are broadcast over `Phoenix.PubSub` by
  `RiskEngine.RiskBroadcaster` so that dashboards and downstream consumers
  can react to risk changes as they happen.

  See `RiskEngine.Application` for the supervision tree.
