/**
 * Fetch a vault's full capital exposure from the Untangled portfolio API.
 *
 * Untangled reconciles Stellar vaults end to end — the vault's idle buffer,
 * capital deployed into Stellar protocols, custody wallet balances, and value
 * bridged to other chains. DeBank and Octav.fi cover none of that, which is why
 * Stellar vaults previously rendered an empty exposure breakdown.
 *
 * The endpoint is keyed by **vault** address and already aggregates every
 * borrower, so it must be called once per vault — never once per borrower, which
 * would multiply the same totals.
 *
 * Requests are plain `GET`s with no custom headers. That is deliberate: it keeps
 * them preflight-free in the browser, where the API's `access-control-allow-origin: *`
 * covers the simple request but a bare `OPTIONS` is rejected.
 *
 * Never throws. Every failure — unknown vault, upstream error, transport
 * failure, malformed body — resolves to `null` so callers can degrade to an
 * empty exposure section instead of losing the rest of their response.
 *
 * Worst case: exactly **1 HTTP call**. No retry, no caching (the API is edge
 * cached at `s-maxage=60`, well inside its 60 req/min budget for one call per
 * vault page load).
 *
 * @param vault - Vault address, e.g. a Stellar contract address (`C…`).
 * @returns The resolved exposure report, or `null` when Untangled does not
 *   reconcile this vault or the request failed.
 *
 * @example
 * ```typescript
 * const exposure = await fetchUntangledVaultExposure(
 *   'CCL3WITWFFXIHV2I52ECV5DPIEOFSTU3PBPR53ILPLF2IP5KHECXRUTY',
 * );
 * // exposure?.tvlUsd     → 24845637.05
 * // exposure?.byProtocol → [{ protocolId: 'stellar-wallet', … }, { protocolId: 'blend', … }, …]
 * const normalized = transformUntangledToDebank(exposure);
 * ```
