 | `amy offer info NOFFER` | Decode a `noffer1…` pointer (pubkey, relays, price type/amount). Local, no network. |
-| `amy offer request NOFFER [--amount SATS] [--timeout MS]` | kind:21001 round-trip: publish the request to the pointer's relays and print the returned BOLT11. `--amount` is required for spontaneous offers; fixed offers default to the pointer's price. |
