/**
 * Folds one dex section's account scalars into the running totals.
 *
 * A Hyperliquid strategy wallet is a single unified cross-margin account that
 * the API mirrors as one view per perp DEX (`{ main, xyz, … }`), all sharing
 * ONE USDC collateral pool. The per-field aggregation rule follows from that:
 *
 * - `accountValue` / `withdrawable` describe the WHOLE account. The dex holding
 *   a position reports full equity; every other view reports only free
 *   collateral; and `withdrawable` is identical in every view. So take the
 *   `max()`, NEVER the sum — summing double-counts the shared pool and sizes
 *   `margin_pct` positions ~2× too large.
 * - `totalMarginUsed` / `totalUnrealizedPnl` / `totalNtlPos` are genuine
 *   per-dex usage of the shared pool → sum.
 *
 * Single-collateral-token assumption: this is correct while every dex shares
 * one collateral (today all USDC). A dex on a different collateral (e.g. USDT
 * CASH perps) would need grouping by collateral token — neither max nor sum is
 * exact across collaterals. Equity/withdrawable are non-negative, so the `0`
 * seed is a safe `max()` identity.
