/**
 * BlockRun Gateway price fetcher.
 *
 * One fetcher, many asset classes. Dispatches on `PriceQueryParams.assetClass`
 * to the right Pyth-backed Gateway endpoint:
 *
 *   crypto     → /api/v1/crypto/price/{ticker}         free
 *   fx         → /api/v1/fx/price/{ticker}             free
 *   commodity  → /api/v1/commodity/price/{ticker}      free
 *   stock      → /v1/stocks/{market}/price/{ticker} paid ($0.001 x402) — PR 2
 *
 * PR 1 scope: crypto / fx / commodity only. The stock branch returns a
 * `ProviderError { code: 'insufficient-funds' }` until the x402 signing
 * wrapper lands, so callers get a useful message instead of a wire-level
 * 402.
 *
 * Response shape from Gateway: Pyth delivers `{ price, confidence, timestamp }`
 * — no 24h change, no market cap, no volume. Legacy CoinGecko-shaped fields
 * (`change24hPct`, `volume24hUsd`, `marketCapUsd`) come back as `NaN` for
 * non-crypto classes; views treat NaN as "not applicable" and render a dash.
