/**
 * Thin authenticated fetch client for the remote signing service. Owned by
 * `ServerKeyring` and shared with every registered `ServerChainAdapter` so each
 * chain's adapter can hit the namespace-agnostic routes (`/transaction-requests`,
 * `/signature-requests`, …) without re-implementing auth or error mapping.
 *
 * Errors are translated to typed {@link RemoteSigningError} variants so callers
 * can branch on `code` rather than parse HTTP status codes.
