See what a Drip series audience gave in DonorPerfect

**Objective:** For the Drip email series campaign `{campaign}`, find which of its subscribers made gifts in DonorPerfect in the last `{lookback-days}` days (default 90), and total them.

**Step 1: Identify the campaign in Drip**

Call `drip-get-campaign` with `name.contains` set to `{campaign}`, or with `campaign-id` if `{campaign}` is numeric. If more than one campaign matches, list them (campaign-id, name, status) and stop.

**Step 2: List its subscribers**

Call `drip-get-campaign-subscriber` with `campaign-id` set to the campaign's id.

**Step 3: Find each subscriber's gifts**

For each subscriber, call `donorperfect-get-donor` with `email` set to their email, falling back to `donorperfect-get-address` with the same email. For each donor found, call `donorperfect-get-gift` with `donor-id` set to the donor's id, then keep only gifts whose gift-date falls inside the lookback window. Filter the dates yourself rather than passing gift-date filters, which are unreliable on this connector.

**Step 4: Report**

* A summary line: subscribers in the campaign, how many are DonorPerfect donors, how many gave in the window, and the total amount given.
* A table of givers: name, email, donor-id, number of gifts, amount in the window, and the DonorPerfect campaign codes on those gifts.
* A note on attribution: Drip enrollment shows exposure, not cause. Say whether the DonorPerfect campaign codes on the gifts point to this email series or to something else.

**Rules & Guidelines:**

* `drip-get-campaign` and `drip-get-campaign-subscriber` are on the drip server. `donorperfect-get-donor`, `donorperfect-get-address` and `donorperfect-get-gift` are on the donorperfect server.
* This prompt is read-only. Do not call `donorperfect-save-gift`, `donorperfect-save-contact` or any Drip action such as `drip-remove-subscriber-from-campaign`.
* Drip campaign ids and DonorPerfect campaign codes are different things. Never treat one as the other.

**Validation:**

* If the campaign has no subscribers, say so and stop.
* If no subscriber is a DonorPerfect donor, report that rather than a zero total.
