Check Shopify sales tax against your Rillet tax account

**Objective:** Compare the sales tax Shopify collected on orders from `{from-date}` to `{to-date}` (default: the previous calendar month), net of refunded tax, with the net credits posted to Rillet account `{tax-account-code}` in the same period.

**Step 1: Tax collected in Shopify**

Call `shopify-get-order` with created-at.from and created-at.to set to the period. Leave out orders with cancelled-at set. Sum total-tax by currency.

If the period has 50 orders or fewer, also call `shopify-get-order-tax-line` for each order-id and total shop-price-amount by title, so the report can show the tax by jurisdiction. Above 50 orders, skip the breakdown and say why.

**Step 2: Tax refunded in Shopify**

Call `shopify-get-refund` with created-at.from and created-at.to set to the period. For each refund-id, call `shopify-get-refund-line` filtered by order-refund-id and sum total-tax.

**Step 3: Tax posted in Rillet**

Call `rillet-get-accounts` filtered by account-code `{tax-account-code}` and confirm it exists. Then call `rillet-get-journal-entry-lines` (no filters) and keep lines whose account-code is `{tax-account-code}` and whose date falls in the period. Net them as credits minus debits, by currency.

**Step 4: Report**

A table by currency:

| | Amount |
|---|---|
| Shopify tax collected | |
| Shopify tax refunded | |
| Shopify net tax | |
| Rillet net credits to the tax account | |
| Difference | |

Then the jurisdiction breakdown if you have it.

If there is a difference, look for its likely causes and list them: refunds booked in a different period, orders not yet invoiced in Rillet (check `rillet-get-invoices` for invoice-numbers equal to the order names, with or without #), or tax filings posted to the same account.

**Rules & Guidelines:**

* `shopify-get-order`, `shopify-get-order-tax-line`, `shopify-get-refund` and `shopify-get-refund-line` are on the shopify server. `rillet-get-accounts`, `rillet-get-journal-entry-lines` and `rillet-get-invoices` are on the rillet server.
* This prompt is read-only. Do not call `rillet-add-journal-entry`, `rillet-update-journal-entry` or any other write tool.

**Validation:**

* If `{tax-account-code}` is not a Rillet account, stop and say so.
* If there are no Shopify orders in the period, report Shopify tax as zero and still show the Rillet side.
* Show every currency separately. Do not convert.
