+ *   2. balance pre-check (sum across all restaurants in the cart)
+ *   3. POST /orders → { order, invoice }
+ *   4. (optional, customer choice) POST /api/v1/payments to settle
+ *      the bolt11 from the customer's LNbits wallet. They can also
+ *      skip this step and scan the QR with any other wallet — the
+ *      extension's invoice listener marks the order paid either way.
+ *
+ * Split into two distinct actions so the UI can render the QR codes
+ * between place and pay, giving the customer the option to scan
+ * with an external wallet rather than auto-paying from LNbits:
+ *
+ *   placeOrders()    — runs steps 1-3, populates `state.value.placedOrders`
+ *   payOrder(idx)    — runs step 4 for one placed-order index
+ *
+ * The festival aggregator (aiolabs/restaurant#8) exercises this same
+ * path with N > 1 restaurants in the cart. v1 happens to ship a UI
+ * where N == 1, but the orchestration is multi-restaurant ready.
+ *

+ * `buildCreateOrder` helper — single point both REST and Nostr
+ * transports construct CreateOrder. Loyalty (#5) injects its

+ * RestaurantNostrSync — live overlay for menu item state via NIP-99.
+ *
+ * Subscribes to the restaurant's `nostr_pubkey` for:
+ *   - kind 30402 (NIP-99 classified listings) tagged
+ *     `["l", "restaurant:<restaurant.id>"]`
+ *   - kind 5    (NIP-09 deletion requests)
+ *
+ * Each incoming 30402 is parsed into a partial MenuItem patch keyed
+ * by the `d` tag (= menu item id) and pushed to a reactive overlay
+ * map. `useMenu` merges this overlay into its `items` computed so
+ * price changes, sold-out flips, and availability updates render
+ * within ~1s of the operator's edit on the extension side.
+ *
+ * Subscription lifecycle is owned by the *consumer* (RestaurantPage
+ * opens on mount, closes on route leave). Visibility integration is
+ * handled implicitly by the RelayHub — backgrounded tabs lose the
+ * underlying WebSocket; we re-subscribe on the next mount.
+ *
+ * This service holds NO state about which restaurants are subscribed
+ * — it expects callers to track their own sub ids if they need to
+ * tear them down individually.
