+// import { requestAccess, signTransaction, getPublicKey }
+// from '@stellar/freighter-api';
+//
+// With:
+import { useStellarWallet } from '@/hooks/useStellarWallet';
+import { StellarWalletPicker } from '@/components/StellarWalletPicker';
+import { StellarWalletButton } from '@/components/StellarWalletButton';

+// ── WALLET PATCH 2 ── Inside the StellarReceive component function,
+// replace the existing Freighter state + useEffect with:
+//
+// const walletState = useStellarWallet();
+// const { publicKey, status, signTransaction, openPicker } = walletState;
+//
+// Replace every call to the Freighter API:
+// requestAccess() → walletState.connect(walletState.walletId!)
+// getPublicKey() → walletState.publicKey
+// freighterSignTx(xdr, opts) → walletState.signTransaction(xdr, NETWORK_PASSPHRASE)
+
+// ── WALLET PATCH 3 ── In the JSX, replace the old "Connect Freighter" button:
+//
+//
+//
+//
+// StellarWalletPicker renders null when pickerOpen=false, so it can sit
+// anywhere in the component tree safely.
