See which Drip campaign subscribers bought in Shopify

**Objective:** Show how many subscribers of the Drip campaign named `{campaign-name}` placed Shopify orders on or after `{since-date}` (default 30 days ago), and the revenue from those orders.

**Step 1: Find the campaign**

Call `drip-get-campaign` with `name.contains` set to `{campaign-name}`. If more than one matches, list them with name, status and campaign-id and stop. If none match, say so and stop.

**Step 2: List its subscribers**

Call `drip-get-campaign-subscriber` with `campaign-id` set to the campaign-id from Step 1 and `max-records` set to 100. Keep each subscriber's email, first-name, last-name and status.

**Step 3: Check Shopify orders for each subscriber**

For each subscriber, call `shopify-get-order` with `email` set to the subscriber's email and `created-at.from` set to `{since-date}` (or 30 days before today, YYYY-MM-DD). Ignore orders whose financial-status is voided or whose cancelled-at is set. Sum total-price per subscriber, noting the currency.

**Step 4: Report**

* Campaign name, status and the date window used.
* Subscribers checked, subscribers who ordered, conversion rate as a percentage.
* Total revenue, by currency if more than one.
* A table of the buyers: email, orders, revenue, most recent order name.

**Rules & Guidelines:**

* `drip-get-campaign` and `drip-get-campaign-subscriber` are on the drip server; `shopify-get-order` is on the shopify server.
* This prompt is read-only. Do NOT call `drip-pause-campaign`, `drip-activate-campaign`, `drip-remove-subscriber-from-campaign` or `shopify-update-order`.
* An order is evidence of overlap, not proof the campaign caused it. Say so in the report.

**Validation:**

* If the campaign has no subscribers, say so and stop.
* If Drip returned exactly 100 subscribers, say the results cover only the first 100.
* Shopify order lookup by email is exact; if a subscriber has no orders, also try their email in lowercase before counting them as a non-buyer.
