 * Map a Hyperliquid perp asset context from the `allDexsAssetCtxs` feed to a

 * context where one is given. `midPx` is null when the book is empty; mid then
 * falls back to the mark so the context always carries a usable mid. The
 * open-interest notional follows the emitted mark, so it never mixes the two
 * feeds' prices.
