 * it to a bare `buildTokenTransferHostFunction` helper. The demo needs the full
 * SEP-41 surface (balance, name/symbol/decimals reads, transfer) for token UX,
 * which a transfer-only host-function builder cannot provide. We ALSO expose
 * {@link buildTokenTransferHostFunction} for the low-level relayer `{func,auth}`
 * path. (`sac-sdk` regeneration from a canonical source is handled in B4.)
