/* ============================================================================
 * UltrafastSecp256k1 -- Error Model
 * ============================================================================
 * Every ufsecp_* function returns ufsecp_error_t (0 = success).
 * For detailed diagnostics, call ufsecp_last_error() / ufsecp_last_error_msg()
 * on the context that returned the error.
 *
 * Thread safety: each ufsecp_ctx owns its own last-error slot.
